What Are Rocks and How Do They Form? Crash Course Geography #18

From towering mountains to pebbles along a river, the Earth is made of a huge variety of rocks. In today's episode, we're going to follow the rock cycle of a piece of granite in the Himalayan mountains, and as you'll see, every rock has a far-reaching story to tell often millions of years in the making.

[@BattletoDeath]

This video was rock solid.

[@nafiaus]

you're fired

[@radagastwiz]

Holy schist, this was a gneiss episode. Won't take this series for granite, that's for sure!

[@th3n3wk1dd]

Rock 1: I think I want to go through a change Rock 2: Really? what change? Rock 1: Probably a harder rock type! Rock 2: Gneiss.

[@1mcob]

Wow. This is a huge scientific description of our earth's surface. Bravo.

[@kingston872]

Would love to see a crash course geology as well. I majored in geology minored in geography. Looooove earth science 🙂🙂🙂

[@soracandles1979]

If I may ask what type of job did you get with your geology degree? I’m really interested in geology

[@heitorkovalescki6613]

Strongly agree

[@timofeypetrenko2264]

Yeah, it would be great to see them cover basics of Physical Geology, Historical Geology & Paleontology, Minerals & Rocks and geological structures.

[@tbeller80]

The Great Courses series on geology is taught by a guy with degrees in both geology and chemistry and he puts both of them to use in his lectures.

[@kusuosaiki6590]

arent rocks amazing💗

[@1.4142]

This is a gneiss video. Rocks are not to be taken for granite.

[@th3n3wk1dd]

Gneiss Pun for sure!

[@jamiehackl1231]

This is the best crash course series with the best presenter! The knowledge, the confidence, the enthusiasm! Absolutely beyond reproach! Not to mention the hair, the nails, the shirt. Alize you're amazing!

[@ctkachuk08]

This episode rocks! I’ll let myself out…..

[@matthewblijd4201]

Then i'll call the FBI to bring you back in!!

[@philipseven9215]

Thank you so much Crash Course! I'm fine with intertwining geology (concepts) with Crash Course Geography even if getting a standalone geology Crash Course is not likely.

[@jdlenl]

brb going back to college to become a minerologist p.s. love the lapis lazuli earrings

[@gy2gy246]

This is geology, which builds the features of geography

[@salmahajjaji]

I don't have enough words to express my love to this educational channel i love you guys I've learned a lot feom u with a simple methods for explaining

[@dinohall2595]

This episode really rocked. I'll see myself out...

[@JV-km9xk]

#18 already? Time flies.

[@ZachSavoy]

i love all of you

[@sagarpraveen-n6z]

There seems to be an error @2.32. Earth's core is said as 960km in radius but the animation shows 960km as diameter

[@norawallberg1345]

Thank you! Interesting!

[@commandosh33p]

Fantastic!

[@steve3847]

They’re minerals. Jesus Christ Marie

[@lukeskinwalker922]

They’re minerals!

[@ranewanders8147]

Great video! Although, I'm curious why you gave the mountain granite such an ego identity? I'm a bit distracted thinking about what that implies, like an ocean wave afraid to hit the shore because it'll crash and die 🌊

[@collindsouza4735]

Ultimate narration and easy to understand for one and all.. thank you guys...

[@endrawes0]

Wow. Very informational.

[@deeez00]

Nice video

[@b800294]

What does a geologist say when they see an attractive metamorphic rock? Gneiss!

[@donkeyhobo34]

They're not rocks, they're minerals

[@ryanratcliff2726]

I'm trying to figure out what is the pattern on Alize's shirt. It looks kinda like birds and kinda like dinosaurs but not too much like either.

[@ShakyHades]

stop making me sad about soil and rock characters, thought café :(

[@duraikannan5315]

Imagine if rocks have a rock band

[@breid361]

Rocks

[@KannikCat]

"Which is made with the help of all these gneiss people..." I knew the Crash Course team were all rock stars! :D

[@coensamazingworld6340]

❤

[@DeuryMota]

Okay

[@rizdalegend]

Actually water is the most universal solvent.

[@BusinessBasics]

I was going to leave a geology joke, but I couldn't dig one up 😒

[@zak94ghost92]

Got for homework

[@thomasalford7678]

Shouldn’t it be CrashCourse *Geology?

[@georgefspicka5483]

I love your explanation of erosion (starts at 6:10)

[@juliegolick]

Am I the only person who felt bad for the poor little granite rock?

[@OutdoorCanadians]

This reminds me why I failed geography 😂

[@pedapudidiwakar77]

I don't know why I'm here but yeah...

[@sundaymacdonald2882]

Plot twist: all rocks are from Rockstars😎

[@gvsingh8750]

"No one has ever gone to centre of the earth", Ask Jules Verne he will tell you all about that.

[@funnygrunt_o7]

I love the shout out to the aboriginal peoples. I wish we all could be proud of a place we originated from and weren’t thrust into someone else’s home by those who came before us.

[@Justin-cw7zf]

Rocks really, rock, don’t they? Anyone? Hello?

[@michellemartinez9767]

supe

[@HexerPsy]

Your aunt must have a heart of stone. *badumtiss*

[@rontocknell5400]

Why 'crash course in GEOGRAPY rather than Geology?

[@Nai-qk4vp]

JESUS , MARIE THEY'RE MINERALS!

[@tjofftjoff5107]

The plural of process is not pronounced "processeez", you're confusing it with the pluralization of Latin words ending with -is, such as axis or analysis. Processes has a standard English plural. Thanks for coming to my TED talk!

[@psychod7481]

First xd

[@lj53004]

I've never felt so much empathy for a slab of granite before. Poor thing lol

[@idealworld321]

❤

[@Rebelnightwolfe]

There are actually two types of crust on Earth; thin crust and stuffed crust.

[@IceWolfTO]

This ten minute video explained a large part of my first semester of studying Geology so well.

[@luminariastormreaver]

Rock on! Lol

[@ancientswordrage]

Rock out!

[@hunterG60k]

I was fascinated with rocks as a kid, I even had a collection of granite stones that were different colours. Sadly, one day my sister chose to use the container housing said stones as a weapon; I lost a tooth; and some of my passion for rock collecting lol

[@matthewblijd4201]

In the words of Spiderman Noir (from Spiderman into the spiderverse): That's a hardcore origin story!! P.S--> I take it that that's the reason you became a horse?

[@shockingheaven]

9 year-old me would be so happy watching this video, so I'm doing it for her

[@Iisa1010]

I am a geoscientist and there are rocks in every corner of my room. Picked them up on field trips, now they are just vibing. Love them, they bring me joy

[@SupermaxLaFrom]

Wow I didn't know I was into rocks until now!

[@cyto3338]

Jesus Christ Marie they are Minerals

[@danieljensch3754]

Rocks are awesome!

[@jsparakov]

They're not rocks. They're minerals!

[@EdBabb]

Damnit Marie!

[@LuminalSpoon]

Jesus Christ Marie

[@_evillevi]

Me: yeah I gotta do lots of stuff I'm long overdue Me later: YOU ARE RIGHT WHAT ARE ROCKS???

[@craigmooring2091]

So when you find a gneiss-looking rock, don't take it for granite.

[@samyciuta493]

This rocks!! ❤️😁

[@hubijohn7451]

I've been waiting for geology vids for so long! Yeah!

[@MrARock001]

That was a huge amount of information packed into a 10 minute video. We might even say you could do a whole Crash Course series on Geology!

[@Thecutekirby]

Who else is watching this for science I V

[@listenchump4041]

6:55 poor little granite rock :(

[@frostliquid843]

Ayy Alizé had a new hairstyle, she looks gorgeous. And as always, I really appreciate all of the team' work in order to deliver to us viewer quality educational videos, they really spark my interest for geographic stuffs. Thank you very much.

[@ACEPLAYZ_7]

I have to watch this because of school

[@1898time]

This wins first prize for how fast to talk. Couldn’t listen any longer.

[@androidbox3571]

I think you are confusing geology with geography.

[@kevinhardy8997]

First you need a sick drummer.

[@taimalik1110]

This video was approved by The Rock!

[@davidchen3503]

why speak so fast?

[@timofeypetrenko2264]

CrashCourse Geology?

[@tamiimho6622]

I love all the comments from people knowing the difference between Geography (Earth Mapping) and Geology (Earth Study).

[@kvpranes1638]

hooooyaaa

[@rosearah]

Earth science is so underrated

[@DonMarzzoni]

Geology is the Kardashians of science - Sheldon

[@Addis0]

Hahahah.

[@lakrids-pibe]

What is this? A rock collection for aunts?

[@storyspren]

It's not just a stupid boulder! It's a rock!

[@XanderGouws]

I have the smallest possible gripe with this video. At 2:34, Alize says 'radius of 960 km', but the graphic in the video shows that the diameter is 960 km. Ultimately not important, but just wanted to point it out in case you guys decide to reupload.

[@lisadawson2652]

Very detailed video however the speaker talks very fast text is definitely needed 👍🏾

[@rizkyfajar2393]

Make Crash Course Geologyyyyy

[@esphilee]

Rocks are form by Drum, Electric Guitar, Bass Guitar, Keyboard.

[@derekkey2803]

Hank Schrader would be proud that I learned the difference between rocks and minerals today.

[@ad.7328]

Jesus Christ Marie! They're minerals!

[@fergimedia]

Love these educational videos !!!! My son and I really enjoy these a lot !! Thank you for putting these out !! Love from Winnipeg, Manitoba, Canada 💕

[@Elicosmic777]

Nice Lapis earrings :)

[@dr.ashishgopaldewan1225]

Loved the learning.

[@samanthatroi85]

I'm doing a presentation on geology and I spent all last week searching for Crash Course explaining the rock cycle. So glad this is now here

[@chenecaddell]

Very interesting. Not one Led Zeppelin reference though.

[@Sharksaretoosilly]

This video “Rocks”

[@delecti]

Aww, why'd you have to make the disintegrating rock so cute?

[@JohnChaffer-cd4bt]

Is this a colledge graduating class of 2024 orientation to the real world

[@Noah_CT]

This video rocks man

[@xaviertayo6208]

I barely understood any of this.😢

[@TurboKingCandy]

New rock video! Gneiss.
