I’m developing a late life interest in surficial geology, trying to understand how the fascinating shapes on the eastern edge of the Williston basin formed. Really appreciate this info. There is a comment though that heat keeps some of the sediment “up”. It’s common knowledge that “heat rises”. Except it’s not true. There’s no law of physics that makes heat “rise”. In a solid it will conduct, generally more in the direction from hot to cold. Entropy. In a fluid, gravity will act more strongly on the cooler (and denser) groups of molecules, pulling towards the gravitational “bowl”. I may be splitting hairs although understanding gravity’s role in the physics of fires, including campfires, can be…. illuminating. Consider the magic, the invisible tongues of cold air being pulled into the depths of the fire by gravity, in perfect counterpart to the visible flames shooting into the air, where the cold dense air rapidly displaces the suddenly, explosively lighter gases of combustion. Is heat really holding things up?
Even with my BS, I still love coming back to learn about subjects that weren't taught in my program. Thank you for providing these.

Thanks Matthew for ShareThis
ευχαριστώ πολύ, εξαιρετικός
Thank you Matthew ☺
it is vary useful for me, thanks you
Thanks a lot sir, this video was very helpful
Hi, Can you tell me, where did you obtain (paper/article) the image at the minute 10:18 of the Western of North America?. Thanks!
Matthew 고마워요
How can you be thorough and compact at the same time?
Thank you man
What is types of subsidence ?
Aesthenosphere is not liquid!
