Good video. You might want to do a video comparing river erosion with glacial erosion. I remember being taught that glaciers were big ice bulldozers grinding away the rock underneath, kind of like a stream. But then why the U-shaped valleys? Climbing along the glacial arete in Kamikochi Japan made me aware of the real power of glaciers- the freeze, expand cracking all along the sides of a glacier - quarrying. Aretes are usually what's left over as glaciers quarry but recede too rapidly to then transport the shattered rock. It's pretty exciting to know that with hundreds of meters of space below your butt, the rock you're holding on to is all broken (and bats hiding in the cracks are hissing.

When I found out during my visits to the ancient -seaport- towns of Miletus and Priene that -seashore- today is 4 hours of walking distance from the remnants of the stone piers, I respectfully realized what a river is capable of doing to the landscape over time. Nature doesn't care much on the long run, about how much you've invested in your seaport and a whole town surrounding it. :)

Very grateful that crash course makes an effort to incorporate a more complete worldview in its videos than the america-centric or western perspective usually found in class. Rather than hear about the Mississippi or Colorado rivers today like I have for years, I learned about rivers with the Zambezi river system as a core example. Thank you!

I know one thing. If the river is going in a certain direction, that's generally down hill and the easier way to go. Just go with the flow. At least until there's a waterfall.

As a geomorphologist, I just wanna say thanks for finally giving our field some Crash Course representation! I love that this has become just a general Earth Science course.

I-m really excited for the human geography portion starting soon. It-s a really interesting subject and I-m glad it-s being covered in crash course

What places is this stock footage from? Do you have a link for the source footage you used, or where the places are?
Like 1: 00. Where is that?
