You've never observed, nor can you repeat 66 billion years. This is not science.
@@ajvandelay8318 Moron. I'm a time traveller and can report that the Romans dug the Great Glen.
@@ajvandelay8318 That is not what "observation" means. You are conflating "observation" with "watching"
Oh that is hilarious. Dear Scotsman. We call that a dad joke here :-)

Have a look at the Highland Boundary Fault further south, which separates the Highlands from the Lowlands. The small town of Comrie in Perthshire is known as "shaky toun" as it's right on the fault and gets dozens of small tremors a year. It even has the world's first seismology station, built in 1840. It's a lovely area to visit with fantastic scenery.
Haha that’s where I live!
I live just above the Highland Boundary Fault, on the Loch Long Fault. I remember experiencing an earthquake here in 1985. It was quite a loud bang followed by a violent shoogle. I thought there had been an explosion nearby and that our house had slipped down the hill. Of course it hadn’t but an earthquake isn’t the first thing that comes to mind when you experience something like that in Scotland.
@@kirsteneasdale5707 so you guys are directly on a fault and you have tremors but no big earthquakes?
@@jal-kx6tmprecisely. I'm certainly not a geologist but I guess the strength of the quakes depend on how "active" a fault line is. The ones in Scotland don't move that much these days, hence the quakes are small.
That's my understanding, at least 😂
Interesting - I’m in Montrose and not heard of Comrie
Greetings from Scotland. I'm a highlander and it's definitely my fault!

Geology itself is basically the fault of the Scottish
Check out the Geology videos in this playlist I made, there alot of stuff about Scotland, y'all basically made modern Geology

Fellow scot. Underrated comment.
I'm a glaswegian!
Greetings from the US. I'm a New Englander and it's definitely my sister's fault.
Slightly further south is the Iapetus Suture, which is what separates the Laurentian plate from the Avalonian plate. It runs close to the Scottish border, down through the Isle of Man where you can actually see the bare rocks, and through Ireland down to the Shannon Estuary. It's had a huge effect on history.
Cool! Thank you!!!!
Noice!
All I saw was plates, now I'm hungry
Y
Such knowledge . Dope
I remember a Scottish person telling me that Scotland was wandering around the oceans and it could have run into any country, but it had to run into fookin' England.
England stole it from north America. And Noway tried to nick Greenland as well.
Lol😂🏴
Not surprised, we tend to live in their heads rent free
@@darkstarr2321 some English , not all 🏴
Yeah ......sounds like the typical whingeing Scot ?
A lot of my PhD was on this. I studied how magnetic fields interact with the carbon in the Iapetus Suture and Variscan orogenic faults and this enabled me to find where the former ancient ocean bed residue was, and allowed me to make 3D models of the Earth's crust in Ireland.
Now that is cool.
That's amazing 👏 I'd love to see it. Is it available online?
Interesting
Now that’s the coolest thing I’ve heard in a while!
Yes! We’d love to see your work!
When you travel from one side of the fault line to the other, due to the plates being made of different types of rock the scenery changes completely. From a brownish, rounded-off quality to the hills and mountains in the east, to pure grey granite with very little coverage of moss and plants in the west. It's like suddenly stepping into Austria 🙂
Not dissimilar to the change in the Peak District at the great ridge between Edale and Hope Valley. To the north is sandstone (millstone grit), forming the domed mountains and moors of the Dark Peak; to the south is carboniferous limestone, forming the dales (plateaus and valleys) of the White Peak. The change and contrast is sudden and dramatic.
I can confirm this, I live in the thing, on one out of my bedroom door I see Austria, from my conservatory I see the alps
@@WhippetNose its nothing like the peak district, that doesnt even belong in this conversation
@@IndigoBikeTouring who made you the arbitrator?
Fascinating observation! I must go and see
It did this to make a perfectly straight line for Nessie to swim through when she wants to leave Loch Ness.
Nessie has evaded capture for decades without even having the ability to turn. Magnificent creature
@@MikeFilemaker Magnificent creature....or log.
I thought it was to stop wild haggis roaming to the South
@@Davey-Boyd Wild haggis never leave the mountain they are born on. Interesting fact - they also never move up or down a mountain, they remain at the same elevevation they were at birth because females have longer legs on their left side, males on their right, so females can only walk around the mountain slope clockwise and males anti-clockwise.
Originally, Nessie swam along the Laurentia coast and then almost got trapped in Loch Ness when the continents collided, luckily as you state she can leave along the straight line whenever scientists come to find her :)
hello a scotsman here from glasgow, another thing also is we built the caledonian canal along this fault, so we connected all the lochs and waterways along the full length of scotland, so you can get a boat from the atlantic ocean on the left to the north sea on the right, you can hire boats and do it if you wish.
This government project started in 1803 to allow warships to move readily and safely from the North Sea to the Atlantic. It was completed in 1822 - just as the introduction of iron steamships re-wrote the rule-book leaving it effectively obsolete. It has been used for small freight vessels and, increasingly, pleasure craft.
Aye we know
Sounds nice, maybe would make a good summer holiday adventure? Can you hire a cruiser?
@@philtucker1224 a cruiser ?? its mainly canals along the route so only really hiring a canal boat or a smaller vessel
@ thank Mech, (I had no idea how wide the canal was). Mainly narrow boats then I guess..
Always amazes me as you drive north across it. The total and pretty abrupt change in the scenery. It's a very special place.
Cross that line on the right train route up from London is the MOST amazing experience.
*You have arrived in Scotland!*
Wrong line - *I was thinking of the one far closer to the national border, and it is not as spectacular as the Great Glen.* It's beautiful on it's own though.
It's as you go up the A9 north of Stirling it kicks in
It's stunningly beautiful.

The whole scotland mission I was thinking of this specific line
My first thought hahaha~
It's all Feng Shui.
Since dragons can only run in straight lines, this feature makes Nessie feel at home.
That might be so. I'm Danish so it's definitely not my fault.
Ohh I like that answer.
Nah it’s caused by Excalibur,
It was the final battle

Now, now folks, strictly empirical evidence scientific methodology only 😅
Fun fact! Nearly every Loch in the Great Glen has its own Loch Monster.
"Nessie" in Loch Ness
"Wee Oichy" in Loch Oich
"Lizzie" in Loch Lochy
And even some rare sightings of one in Loch Linnhe
Many of the surrounding Lochs also have their own sightings in Loch Garry, Loch Quoich, Loch Arkaig, Loch Morar, and Loch Sheil.
Personally I think they're all the same species migrating across the highlands through the river systems that connect the lakes together.
This is scientific fact!
Wait, Scotland has a lake that's basically called Lake Lakey????
@ yes
My take, it's a Kelpie that likes using a lizard form, and just runs around messing with people.
So it's the road for time machine 😮
For them to move to future and back.
I live in that valley. The Great Glen. Very scenic.
Can boats go through the valley? Or is it not actually covered in water?
Wow I visited Scotland would love to live in those hills
Tj4234 can you travel from one side of Scotland to the other solely by traveling the Great Glenn fault line valley?
@@ImTHECarlos98 yes they can. There's a canal that runs through it. Only small boats though, it's not a wide canal. The Isle of Skye is the large inner island that looks a bit like a wing. It has some high mountains on it. That's roughly a viewing distance of about 200 miles.
@@Daniel_leading_the_13_Plateans if you stand at the tip of the Great Glenn on its north eastern side, you can actually see the Isle of Skye in the distance (because the Great Glenn is below sea level like the video says).
It's so we can have lochs deep enough to hold monsters in.
The most logical explanation 👍😀 Love it!
And hence the lochness monster
Nah its the Monloch sterness

The geology here (Scotland) is amazing and never fails to leave me in awe.
Loch Awe?
The Line starts just below Easter Ross which is the Easter Half of Ross-shire and Geologically speaking the area is referred to as Ross...
Sutherland is a mini Rockies. Gorgeous.
Edinburgh Castle sits on a dead volcano, not surprised that there’s a “line” running through Scotland. Beautiful country, I’m very lucky to have visited there.
This is a playlist I made, the geology videos talk alot about Scotland, the Scottish basically made modern Geology, it goes into some of the history (Evans is a Geology professor down here in southern Missouri who's been to Scotland and calls it the holy land of geologists)

Yeah, weird - I have more questions than before I watched this video. Bit rubbish really.
As I sat through the video I supposed that he was in preference of a rather older style of portrayal, a few simple diagrams and oration, allowing his audience to picture the imagery for themselves.
Never heard of Google Earth?
The line is a result of things formed during Caledonian Orogeny... So Scotland is an...Orogenous Zone?
Found Eccentrica Gallumbit's YT account.
I know it's a joke, but also, yes, that's the term for a region characterized by mountain-building 😂 geologists have a lot of fun
@@davidnewtown8774 That's awfully gneiss of you not to go after the low-hanging fruit.
@@zadtheinhaler schist, that's the pun I was going to use
The great glen hasn't been an orogenous zone for a very long time - its very old and inactive.
About 300 million years ago, there was quite a massive mountain range called the Central Pangean Mountains. The Scottish Highlands are part of the remnants of those ancient mountains that were once as high as the Himalayas. The Appalachians in the US were also part of that range.
@Ricky Barber balls
I'll quip: I don't think it was called anything 300 millons years ago. 😏😊(😄)
@Ricky Barber No, you're wrong. We know how old something is based on a combination of stratigraphy and actual radiometric dating techniques. It's possible to date some rocks very precisely based on the decay of certain isotope (here's an example: en.wikipedia.org/wiki/Rubidium%E2%80%93strontium_dating). Other times, we can see what order rocks appear and compare this with the local and greater area. If you have any specific questions, feel free to ask.
@@leticiaromano6054 I wouldn't bother. Ricky Barber is obviously willfully ignorant. He doesn't want to learn. He only wants his worldview upheld. His ignorance is his bliss...
You can tell yourself anything, just as someone else can say anything. No one is right
Where the ancient Iapetus Ocean once existed, we now have the Iapetus Suture Zone. It runs more or less parallel to the border, but to the southern side, between the Solway and Lindisfarne. I live right on the western end and in a 5 mile walk across the boundary, the rocks change completely in type, age and amount of deformation. On the English side, subduction of the old seabed caused volcanic islands similar to the Philippines, that were later lifted, glaciated and eroded to form the Lake District while on the north side you have the Scottish Southern Uplands which are missed by most visitors who race past heading to the busier locations further north. It's a fascinating area with shifting geology and borders !
I can tell you that here in Connecticut, on the East side of the river, is definitely proof that Scotland and America did indeed collide. The soil and rocks are the same as they are in Scotland. On the western side of the Connecticut River, the soil and rocks are completely different and have almost none of the same qualities. I’ve lived here for over 50 years and I also enjoy Geology. Specimens are VERY different! 🇺🇸🕊
Namibia also shares geology with areas in Latin America.
@Karen S Hi! You wouldn’t happen to be talking about Devils Hopyard, would you? Lots of crazy noises there! 🕊
I heard something similar from coal miners.
@Karen S Say no more LOL! The 70’s were a great time, as long as you remember them! 🥰
Anyone who is interested in this area should look it up. Haddam Ct. I tried 2X to post a link, however I guess it went against the rules or something, because it doesn’t show up in these comments! 🕊🇺🇸
Was hoping you'd mention the Scottish Highlands were once connected to America's Appalachia
Indeed ithey were. Some of the most ancient mountainous areas in Scotland were once part ofthe Central Pangean Mountains, which include the Appalachians, the Little Atlas of Morrocco and much of the Scottish Highlands. Here's a bit on the Great Glen Fault, which actually continues on the other side of the Atlantic:
en.wikipedia.org/wiki/Great_Glen_Fault
The Highlands are still connected to Appalachia, in the hearts of thousands of Scottish descendants!
@@rogermac358 funny, when I read the ops comment that's what I thought of.
Yea. Too bad they didn’t
My Scottish ancestors (really only a few generations ago) from the Highlands settled along the Appalachians here in New England. Makes sense they felt at home here! I long to visit the Highlands someday and our ancestral castle. Long live Scotland!
Who's Fault Is It Anyway?
A new geology comedy show.
Coming soon to a RUclips channel near you!
"Scotland, this is all YOUR fault!"
The Fault In Our Scars ... er, geological scars.
There’s definitely a Trainspotting quote that belongs in here 😂
My fault too. Those of us educated locally who took Geography to Higher are pretty familiar with all the details. That straight line extends way beyond the sea shore at Caol or Inverness and can be seen extending at least to Mull and perhaps Islay and Jura in the South and to Tarbat Ness and maybe even Wick in the North. As major faults go, it's pretty quiet. Earthquakes in the UK are almost all less than 4.5 and activity here is usually a lot less than that. Only one event directly on the fault in the last 60 days (BGS) and it was 0.8.
The glaciation has carved out a trench that reaches down to around 300m to 400m below sea level and at four places along this trench it is filled with glacio-fluvial deposits to above sea level. These allow Fort William, Laggan, Fort Augustus and Inverness to provide home for around 70,000 people and prevents there being two separate islands. Loch Ness is the largest and best known of the lochs that fill the gaps between these plugs of sand and gravel. It has a muddy flat-bottom due to deposition from huge catchment area and is a maximum of 223m deep (surface elevation 16m).
I always get a laugh when construction projects run by people from elsewhere start drilling in central Inverness trying to find bedrock without understanding that it is several hundred metres down. The BGS database clearly shows results from a 19th century drill exploration to nearly 100m and all it shows is sand and gravel with occasional minor clay deposits. The buildings all seem to stay up!
Its a Problem we know from Fault Lines where stress builds up only very slowly (if at all): We don´t know what they are capable for. Strong Quakes on such Faults are rather 1 in a 1000 or 10 000 Years events. The Fault line (or fault system) is certainly still active. I could imagine a new Episode of Activity started after the End of the last Ice Age when the Retreating Ice Cover let the ground bounce back which induced pressure onto the Faults.
Quakes which could be attributed to the Great Glenn or nearby Faults are a 4.3 (USGS) in 1974 and a 4.2 (USGS) in 1986. Noteworthy also a 4.6 (+/- 0.3) near Inverness in 1816 with Intensity 7-8 (via Archive of European Earthquake Data). A 1 in 1000(0) Years Quake could easily be a M6 one.
I can tell it ain't my fault. I'm from Denmark. But nice and interesting fault.
Great Comment:) Very interesting I live on Vancouver BC Canada this is on the Pacific Ring of fire 🌋 we have active volcano/ earthquakes
So interesting that the Scottish Highlands and the Appalachians once connected. There is also another weird absolutely straight line valley in Tennessee called the Sequatchie Valley, where I grew up. It’s clearly visible on Google Earth.
Add to that the St. Lawrence Seaway, which is Lake Erie, Lake Ontario and the St. Lawrence River, which form an almost straight line along the northern edge of the Appalachians and the two lakes are part of the border between Canada & U.S..
Maybe that’s why so many Scottish people settled in the Appalachian Mountains
@@thomasshepard6030no, that's where the English on the shephelah forced us to live. They wanted us as a shield against the Native Americans, and had no intention of letting us live with them. Yes Walden Ridge runs from TN to Europe it plays out in Germany.
@ronaldharding3927 that's interesting, I always thought prospecting and mining drew people into those mountains. I'm English but I live in Scotland. I'm interested in the history of the interior of the United States. Its not something we learn much about in the UK. Everything we hear revolves around New York and Los Angeles.

Have you ever done an episode that talks about the Appalachian Mountains and the Scottish Highlands being a part of the same mountain range?
Not just those two, big parts of the norwegian mountains are also part of the same orogeny.
Atlas mountains too or evidence suggests they are
Plus the Blue Stack mountains in Donegal, Ireland and the little Atlas mountains in Morocco. I think.
that map illustration at 0:45 shows the border between England and Scotland, not the line in the Highlands. It's about 150 miles off...
It is not supposed to show the line in the highlands, that part comes right after with the fault lines, it‘s just an overlay of the modern political map of the island for illustrative purposes

That man was James Hutton. Also from Scotland.
James Hutton born 1726 - died 1797, from Scotland is known as the father of geology.
Thank you for this. Whenever I watch, listen or read about similar matters, I become aware just how insignificant and temporary our lives are. The idea of describing 66 million years as ‘relatively recent’ event, blows my mind, and strangely, I get it. I understand the timeline and I feel it as recent.
Our lives are temporary yet... very significant. In the short time we will be here, we appreciably alter the blue marble we live upon. If only we were less consumptive and w stop creating plastics. All together now...group hug! I do understand what you are saying however. Thanks
I've been wondering why there is a line in Scotland for a while but never had the balls to figure out. God bless you for making this
"the balls"? I think there's a reason you couldn't figure it out, but somebody else will have to explain.
It was really my grandad in his JCB that caused it. 😂
Always wondered about that straight line, thought it was glacial activity. Never realised it was originally caused by tectonic plates. Awesome, thanks!
Asks "why don't we see more strait lines in geology like this?" and then proceeds to ignore his own question and move on without even an attempted answer.
He mentioned the reasons: ice age carving and surface features. He just didn't say things like, "first" or "also" or "another reason is". But he did answer it.
@@ericvanzytveld9034 he explained how this happened, but not why we don't see more of it.
@@joshuadempsey5281: it's also a 2-min video. I'd expect he'd say more if he made a 5-min video. It's also possible it's that rare, that just the right set of circumstances worked. Other locations have different sets and different results.
@@joshuadempsey5281
Partly because its not always straight. The San Andreas Fault in California is the same type of strike-slip fault between two plates but its bent due to the Sierra Nevadas. Southern California is where it bends. In many places where two plates are against each other the plates are moving towards each other. Such as India into Asia or Africa into Eurasia.
Freaks of nature? There's a straight mountain valley in the Canadian Rockies that is 600 miles long. Those are rugged upthrust mountains and geologists have no idea how the crust managed to break in a straight line for that far.
I haven';t even seen the entire video yet. However I have the reason for the split. It is simply where "The Wall in the North" used to be, made of 1000ft of solid ice. Castle Black was the main fortification guarding the wall but there was also Eastwatch and many others. Thank you for coming to my TED talk.
They didn't even mention that the larger part of the Laurentian plate that adjoined Scotland is now the Laurentian Shield part of North America, mostly in Canada.
This video was about part of Scotland. It's not always about North America.
You’d think the extra info would be educational enough to include, you know, also to add more to an already short video

There's a similar fault on the southeast/eastern shore of the Great Slave Lake in Canada. The Great Slave Lake Shear zone runs through there, and can be seen from space, despite it not being active in well over a billion years. It is from the Taltson- Thelon Orogeny, and is related to the Trans-Hudson Orogeny, which formed the geologic core of Laurentia 2 billion years ago.
Geology is always so facinating. I love the sloooow march of the tectonic plates always in sloooow motion, except the bursts of crazy activity!🏔🌍🌎⚡

Maybe he meant to say something like “They reveal what they have carved up when they recede” 🤔
@@vice.nor.virtue so they meant to not be wrong
@@maxpulido4268 yeahhh. They didn’t really hit all the nails squarely on the head with this video. 🧐
Something I have always wanted to know, but never bothered to find out, so glad this has shown up in my feed today.
I always wondered too tbh, I am into war map games and seeing the valley line on Scotland made me curious.
I'm really, really happy that SciShow has moved on to a new font. It's so much cleaner and respectable.
I really really hate how companies are dumbing down their logos and making them look "cleaner". Google, Firefox, Microsoft, Patreon, Pringles, Starbucks, many many more, and now SciShow. It makes them look like something from a highschool freshman art project.
@@ThoroughlyBaked I don't know how I feel about the logo change. But I mean the in-video font. I think it's sublime. 🥰
I actually don't like it. :( I was disappointed in the change. But at least someone appreciates it.
@@sweetsingin fair enough. Everybody has an opinion, but I'm not a fan and think it's part of the same trend I mentioned with the logos.

Im a bit worried with the algorythm because i was looking at google maps yesterday wondering this and then this video was top recomendation today
Imagine an earthquake so bad your neighbor now lives 29 km away...
Furthermore, the Scottish lochs are so deep they hold over 90% of the UK's fresh water. Loch Ness alone has more than all of England and Wales put together.
@anon anon The rain 🌧️
Only because us English allow it
They're natural lakes too. Most lakes in England and Wales are reservoirs.
@@audie-cashstack-uk4881 How exactly do we English allow it? Last time I checked weather control wasn't one of our abilities?
@@audie-cashstack-uk4881what????? What you gonna do drain our lochs???
I live in Scotland and I didn’t know this
Same!
A no-nonsense high-speed presentation riddled with insights and facts? to me that deserves a tick and a subscribe which I've just done :)
Ditto!
Quite the coincidence. Was talking to my pal about this recently when we were hiking in the Cairngorms!
did ye aye?
I've walked the entire length! It's a lovely place.
What is also interesting is that the brown rocky formations around the GGL are molecularly exactly the same rock that New England “Brown Stones” are made from.
I´d guess it´s really the same rock. The oldest central parts of the Appalachians are also Caledonian Orogenesis, and the North Atlantic opened much later and tore Laurasia apart, so parts of the same old Brown Stones are now on both sides of the pond.
Yet another reason John Muir felt so at home in California ❤😇
An interest addition to this video is that the geology on each side of the straight fault line is widely different...different rock types, different formations,
different fossil remains and different rivers which stop at the fault, never crossing it.
I believe that one side clearly matches Labrador on the other side of the Atlantic.
Thanks for writing that.
It was the question on my mind as soon as I watched this youtube.
@@russellparratt9859
Hi Russell.
No trained expert I, but a fascinated reader.
Can't offer proof but what I have read over the years. (We don't keep confirmed evidence of that, do we?)
That mapped straight line caught my attention years ago.
@Alboito Einschtien
No. There is a WIDE difference (wide variation) in geology, not a WILD one.
Didn't you mean to put a question mark on the end of yours?
Thanks Alboito.
@@MauriatOttolink I mainly read history, but I have always had an interest in various aspects of science, including geology and palaeontology, even if I don't have the time to pursue these things via books these days.
There is only so much time in a day.......
@@russellparratt9859
Hi Russell.. We find great unexpected gems for which, time of day just HAS to be expanded.
Scotland is the head to England's body, and the line is the cap. Solved.
Did the Caledonian canal by kayak back in '84. A good trip, despite it snowing on the Loch Ness section.
FYI: The British Isles has several other slices sutured together so it has many different geological features in a relatively small area. It's the study of this microcosm that sparked modern geology and why the British got to name things early on.
Interesting related fact.Cornwall was also joined onto England so has different geology.That's why tin is only found there and not in the rest of Britain.Where Scotland joins to England it is actually the ridgeline on which Hadrians Wall is built.It is rather clifflike in some places as I remember.Same with Ulster bumping into Southern Ireland.Strange to think that Britain was parked up just a swim across from New York City millions of years ago and there were mountains there as high as the Himalayas.That's why buildings can be built so tall in NYC because the bedrock is granite.
Aberdeen is build on granite, with granite.
Aberdeen is also the most radioactive city in Scotland (as far as natural background levels go)
This is due to the area having a high % of granite bedrock and buildings.
Sorry but some of your points are incorrect. The modern day Border of England and Scotland is almost entirely geopolitical. The closest you will get to an actual physical "reason" is the Iapetus suture, which runs reasonably close to the current border but has little to do with it. The ridge line in which Hadrian's wall is built is a structure called the whin sill, and is again nothing to do with the geopolitical border which exists today, Although it was quite an easily defended position on which to construct the old border which ran along Hadrian's wall.
@@bill5974
They built Hadrians wall to stop the people who founded my town nipping down to Roman occupied England on raids, lol…….But they just teamed up with the Gaels and started doing raids by boat 🤣.
@@Acheron666 I pretty much live within a mile of what used to be hadrians wall and am aware of its history. Your point has nothing to do with my point though, not sure why you would bring that up to be honest pal.
Cornwall part of France
I KNOW THIS ONE!!!
The electro archon was fighting a great evil serpent, so with her Musou no Hitotachi, she split the serpent AND the land in two. You can still feel the energy in that area known as balethunder
Genshin Impact player spotted!
I had a motorbike like that. Cheap knock-off.
This guys talking oot his erse.
Its actually historically known as the haggistophiserous valley.
Its name was shortened to Haggis Valley in the early 9th century.... only reason for this was no one could pronounce the name... even when sober.
Haggis breed there from May 1st until June 12th.
Glad to be of some help.
Thank you scissor for all of the great content over the years
Always interesting and subject matter that I never knew anything about
I love it and always look forward when new videos come out
I also enjoy watching some of the older videos again
Keep up the great work
Have a wonderful day today ✨
And just to show how far apart these plates can shift, the Scottish Highlands were also once connected to both the Appalachian Mountains in North America and the Atlas Mountains of northwest Africa.
Relatively recently- 66 million years ago. Still fascinating! I love this channel❤
Good short viddy: I know this fault well, because the Caledonian canal is a superb route for a scenic boat trip, and one I have done very often.
I just want to say it would've been nice to have a visualization of plates moving horizontally vs vertically and how those form mountains and elevations. Because you know, this is a video.
Grey...Yes, I agree; I was expecting him to use his hands and say..."now THIS ( as he moves his hands together ), is what a strike fault is...etc. There are a lot of viewers who have no idea what those geological terms actually mean.
@@marbleman52 me I don't know what that means
@@connernixon9281 ....First of all, do you know what 'Plate Techtonics', or the term 'Continental Drift', or 'Sea-Floor Spreading' means? These terms all generally refer to the same thing. All of the land on the earth's surface, both above and below sea level, is part of a constantly moving series of separate sections of the Mantle that are called Plates. They slowly move all around the earth's surface and when they come into contact with each other they push & grind against each other and form the mountains throughout the world, the volcanoes and many other surface features. A 'Strike Fault' is when two leading edges of plates rub and 'slip' against each other in a horizontal direction.
you don't have an imagination good enough to visualise two things moving against each other? Seriously. You need a picture for that? You don't got a butt? 🤣
So you're saying, Scotland is Earth's orogenous zone.
You kinda dated yourself with that comment, but I won't say anything, old-timer.
Home of the redhead so you tell me, Joe 😜
If you look at a map of Newfoundland, there is a long narrow valley occupied in part by 70 mile long Grand Lake. This lake is part of the exact same transverse fault as Scotland's and was formed at the same time. These faults were caused by the fact that as the continents were colliding, they were independently rotating at different speeds and in different directions.
Great video 🙏🏻going to walk it next year will remember its history. Thanks for sharing
There is something similar in Japan which is visible through Shikoku Island called the Japan Median Tectonic Line. The Kobe earthquake of 1995 was on a branch of it.
The Caledonian canal connects Fort William and Inverness using the lochs along the Great Glen fault and man-made canals and locks.
This isn't true. We dug the ditch to keep the haggis from overrunning us.
I love the enthusiasm but this video is actually wrong! source: I am from Scotland. The 'line' is there as it is directly on our Haggis' feeding strip. Our Haggis only eat on this strip due to electromagnetic activity from the earth. Over the years they have eaten so much the 'line' has gotten wider!
I hope this helps clarify things :)
