I watched this like 5 times already. Watching this is a good preparation for a test.
yea
But what causes the cycles of the earths double torus magnetosphere to increase causing magma to well up every 12,000 years for a 1,000 years?
Continental drift should be called continental rebound after Noah's tidal wave deluges hit up against Africa pushing the mid Atlantic ridge up and tearing the Pacific ring of fire apart.
The galactic Milankovitch cycles not you or co2 causes climate trends and this the millennium of climate change END TIMES.
Jesus God warned us.
I always look for your videos which are very helpful for my Earth Science class. Thank you Mr. Mike Sammartano
Thank you! This helped me more than any class I took in environmental science or geology
You make earth science interesting!
Thanks for ALL your videos, Mike. I watch them often and they're very helpful and informative!
Totally appreciate your videos since 4 years
Outstanding job Mike! Thanks muchly. I really hope you're getting funding to produce your videos.
A GREAT overview of key concepts. This video made helped me understand. Thanks.
This is really what I was looking for. Thank You So Much.
Brilliant video.That explanation wAs the best I have ever seen.Clear and easy to understand.
I really like the way you explain, it's not fast or slow and I can understand it carefully really appreciate you videos. I hope you inspire a lot of teachers to copy the way you teach the calmness and gentle of your voice. love your videos
This is one of the best educational videos I’ve seen on RUclips!
Absolutely amazing explanation ❤️❤️ . This video clarified concepts in great detail 🥰🥰 . Please make more geology/climatology/ oceanography etc. Videos 🙏🏻😊💐💐💐💐💐
This video helped me in how to explain it clearly for my science report. Thank you!
At the end of 13 minutes, I was thinking, is it over already? That was an awesome video. A little long to play in class, but still good, I can play parts of it. And no ads, even better.
Not sure how long your lessons are, but I reckon it's an ideal length to play in class.
Thank you. 💐💐💐Wonderful explanation on “sea floor spreading”.
Thank you very much for this explanation, your presentation was very effective..
Thank you, this helped a lot
Really fascinating.Grateful.
Very nice video, many good pieces of information. However, I would argue that "supporting evidence #3" is better explained by proximity to continental masses than distance from ridges. The sediments come from erosion of areas above seawater. As you can see from the map shown, there is no consistent difference until very close to shore
very pleasing to the eyes! thank u so much, its very detailed and its easy to understand!!
This was f amazing. Particularly the patterns of magnetism on the sea floor. Thanks
A really great video explaining seafloor spreading. I teach 6th-grade special ed, and this was so much easier for my students to understand then the textbook explanation. The narration is gentle and kind, as well. Thanks so much!
I feel embarrassed, we learnt this in year 7 and now in year 9 they are teaching it again! It's good to remember general knowledge though 😆
super interesting and helpful for my studies
NICE EXPLANATION. THANKYOU VERY MUCH!
Awesome explanation !!!
this is so informative, really thankful!
Such an amazing vedio with crisp explanation and animations.
Thanks so much, you helped me ace my test :D
Thank you so much, this video has been super helpful! It's much easier to understand especially with all the helpful images.
Glad it was helpful!
Really awesome video and explanation. Thanks a ton !
thank you for your videos, I'm doing my best to learn
Thanks a bunch!
Wow! Great explanation!❤️
Very Good Explanation
Thanks, this is a wonderful teaching resource!
Glad it was helpful!
Thanks for the explanation 😊.
Excellent explanation. Thankyou!🙏👍
Really enjoyed this. Love the presentation of this as a sequence of supporting the evidence. Thanks
Much appreciated!
Very Nicely Explained!👍🏻👌🏻
Amazing!
Thank you so much
woah. this was one of the most educational video that I've understood
This helped me get a good grade on my test and highly recommended.
this was amazingily well explained......
Thanks for the video sir!
Thank you!
Good Explanation given!
just amazing! like it!
Shout out to Marie Tharp, an absolute legend. 💪
Thanks for explanation
Ur videos help my son a lot keep up the good work
Great job buddy..
Thank you very much.
Very good video
May you make video about histroy of plate tectonic as well... when the term of "plate" start used? Who use this term for the first time?
Nicely explained
Thank you!!
Great explanation 👍👍keep it up 😁😁
it was perfect, from the start to the end
Really helpful
Now I understand, Thank you
Thank you.
Regarding Evidance #1: It would have been beneficial to show what "active faults" mean by layering a map of seismic activity (earthquakes) over the map of ocean ridges and seeing the correlation.
Otherwise, great video! I did not know about sedimentation thickness as evidance!
Very informative
Thank you prof
Tank you so much for the 3rd to help me out with my class in geography
My Favorite part of it pleases me know is that you are very intelligent
Wow, this helped me in my SCHOOL!
Wow this made me suffers in my SCHOOL!
Do you have an additional resource for this specific video (flow chart, notes sheet etc)? Great work and an awesome resource. Thank you.
Amazing
Yess.. you come back.. hi mike... could you make video about stratigraphy or igneous/ sediment structure..? Thanks
Go look at his rock cycle videos.
This was required for school please end my suffering.
Yoo samerzz help!!!!
Yo same

Really helpful 🎉
So glad!
bestvideo on this topic ,, animation is best
Earth is so cool
Thanks
Me: Curling my eyebrows cause I have a presentation for science
Mike: Lemme help you with that
you are better than my science teacher.
how do u explain thr western coast of North America and SouthAmerica also seem to fit together With Austra.
Nice
This is what I call Quality Content.
This is what I call torture
Dam, thought I discovered a channel to subscribe to. But your topics are all over the place. And videos are few and far between.
you taught me more in 13 min than he did in one hour class.
is have a question. as new oceanic crusts are formed, is there a surplus of crustal materials on the Earth's surface?
I'm curious why you didn't talk about the west coast of North America and how that is all newer rock. I'm also wondering why there is no build up of sediment on the west coast if the continent is being pushed west by the seafloor spreading in the Atlantic. Shouldn't there be subduction on the west coat, which would leave sediment build up?
The Rockies were formed by the subduction you speak of. They are a young range, and still growing.
I Like your lesson so you going to be there to help me out with my class in geography lesson💖💖👨
Excellent video! I literally learn more with you rather than with my professors, haha
Awasome
Is it known how the lateral shifts (steps) formed. At visible at 5:38.
What does it mean by the rocks aligning to earths magnetism? Like how does that work
The magnetic bands all have the magnetic field in the same direction. We only have alternating patterns of strength and weakness in the same direction. Wouldn't electromagnetic standing waves produce the same artifacts? With the reversal theory, the magnetic poles have to reverse. Can anyone think how this is possible ?
Can't this evidence be interpreted as in favor of expanding Earth theory over orthodox plate tectonics though?
how do you explain the pacific ocean age on your age map of the sea spreading
They can't with the current plate theory.....
i know and i love it and kinda mad cuz school teaches it as fact i never heard theory attached to plate techtonics or how rain clouds are not just formed from evaporation but also by the suns partical ionizing the atmosphere and getting worst as our magnetosphere weakens to. pisses me off i learn it through the climate change bull sniggels i could smell a mile away and not in a class room where we do go over these subject numerous times in k through12 not once did they say theory and they should have.

A theory that explains the magnetic changes in the Earth's crust is the core remaining as it is, but the earth flipping according to the The Dzhanibekov Effect.
What? 😂
Stretch marks - rapid, and factor in electromagmetic shots recorded in solidified rocks after stretching , noahs flood.
Looks like Earth is expanding
Wow
OCEAN RESOURCES
Problems of developing ocean resources and ways to solve them
Progress in the field of science and technology has made it possible to significantly expand the scope and scale of using the resources and space of the World Ocean.
I'm fucking amazed I finally understood what reverse magnetism is and how the north and south pole works
