    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

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

    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.

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

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

      Strongly agree

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

      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.

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

      Gneiss Pun for sure!

  • @radagastwiz

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

  • @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

    Hey, thanks for the land acknowledgements you include in each of the geography videos. I appreciate that you care about those matters even though they're not talked about. Thank you from a current uni student who's trying to study well!!

  • @meloneusk6184

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

  • @MrARock001
    @MrARock001 3 ปีที่แล้ว +58

    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!

  • @rappar9673
    @rappar9673 6 หลายเดือนก่อน

    wow, as a geologist this one of the best videos to deliver to people who have basic questions about all of this, spares me quite a bit of talking, lol

  • @craigmooring2091

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

    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.

    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.

    Although, I'm curious why you gave the mountain granite such an ego identity?

    like an ocean wave afraid to hit the shore because it'll crash and die 🌊
