Origin of Metamorphic Rocks

- With igneous and sedimentary rocks covered, that leaves just one type of rock to go, metamorphic. What are metamorphic rocks and how do they form? What are the types of metamorphism? Let's learn about this fascinating process!

Dave, are ever going to do a video about the debate you did with Tour? I'd really love to hear some of your after thoughts.
You are amazing thanks for another amazing video!
yeah working on it now
@@ProfessorDaveExplains hey Dave ,
If you do that then please also do some commentary on Capturing christianity's review of your debate which he did with a chemist . Even *clearly stated* commented that that was a great review video.
@@ProfessorDaveExplains can't wait to see it. Thank you for not backing down on calling out James Tour on being a liar. I applaud you not falling for his "come to the board". You were masterful in your deconstruction and he literally had no answers except for "what aboutisms".
@@Mrfunny663vnb83 yep I'm gonna do that too
It'd also be great to cover his nonsense about evolutionary biology, in some other debunking video. There are other suggestions for debunks : Geocentrism (Robert Sungenis documentary), and Quantum Gravity woo (Irwin Klee's documentary). These debunks are very educational, my knowledge about Origin of life research was limited, but after watching and re-watching James Tour's debunks, I started searching and learning. Thanks !
Sweet video, Dave! Thanks for all that you do!
Your geology videos have always been my favorite, thanks alot professor dave, keep it up
5:18 Gneiss? Nice!
You are absolutely AMAZING
you are the best ever
his argument on gender was so poorly made. just as much as Chinese cannot insist that I'm white, XY chromosome person cannot insist I'm female (I'm not talking about a case of gender dysphoria with XXY). also if you're only born as a male, how do you know you're female without never having experienced as female? it's like insisting I'm Martin Luther King because I feel like. what do you mean by that? how can you feel like some other identity without ever expericing the identity?
gender identity is based off of majorly clear binary patterns of sex chromosome. neurochemical expression governed by those chromosomes are within it's bimodal patterns largely because the expression of chromosomes heavily set by preexisting condition whether XX or XY (again not including the exceptional cases with abnormalities (X or XXY, don't mix them up)).
@@JC-sn2hx oh wow… I was watching his interview with mr beat and he wasn’t kidding, even after a year people still are upset with him for… saying trans people exist? Grow up dude, i saw that video and everything he said was fine, maybe controversial but come on
I wish there are more in this series 😢
Edit: ah, i noticed there is😅 such a relief!
You are the best . Thanks 👏
I hope you continue making geology content
thank you
Great analysis, Professor Dave. One quick question: You didn't address the formation conditions for blueschist. Judging by your graphic, this would only form in high pressure, low temperature conditions. I was just curious how such conditions would exist - particularly in areas where continental plates are colliding. Blueschist must be a pretty rare thing, eh?
Blueschists are, in fact, more common than you expect. They form not only in the collision but more often during subduction when the subducted relatively cold oceanic plate gets to high-pressure conditions because it is buried relatively deep under the other (often continental) lithospheric plate (if you go deeper, you'll get eclogite). So you can find them along the recent and past (up to 1 billion years - as I know, they are missing in older formations) active margins of lithospheric plates.
That was a gneiss video.
Very cool video
Professor Dave Ben Dejo explains how rocks are formed.
Hey! How do you recognize pyroxene from amphibole on gneiss for example? I have a petrography test soon and I have to distinguish small pyroxene crystals and give it an aproximate surface percentage. If I miss the pyroxene regardless of how small it is, I inmediately fail the test, ouch
“Slate makes great building stones because of its good cleavage”
truer words have never been spoken.
You explained this better than my teacher
Absolute W
What are the chances the ancient Egyptians had this very information?
do they? if so, so what?
Probably very little. are you talking about them knowing of easily splittable rocks that made good large stones? They definitely knew of that, i think everyone knows of those really easy to work with rocks from that one spot, like the rivers in my area have slate and it’s really cool
Schist happens I guess.
When can we get a Professor Dave Explains TShirt?
I have that! My store should be visible somewhere.
Don christie you here ?
Just got here, how’s the weather, 90’s f around my region
Haha always funny, it's still somewhat comfortable where i live around 27 degrees Celsius (sadly we don't do Fahrenheit)
IMMUNOLOGY!!!!!!!!
Amazing content, can I get a comment heart?❤
Wait did you say heart? I _accidentally_ reported you. Whoopsie doodles!
