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.

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

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

[IceWolfTO]

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

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

[mcob]

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

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.

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

[SupermaxLaFrom]

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

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

[Rebelnightwolfe]

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

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

[MrARock]

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!

[meloneusk]

Crash course on geology and mining engineering is highly needed on this channel.

[hubijohn]

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

[_evillevi]

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

[ctkachuk]

This episode rocks!





I’ll let myself out…..

[shockingheaven]

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

[jdlenl]

brb going back to college to become a minerologist

[philipseven]

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.
