There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on this planet are so easy to figure out. Join Hank for a fascinating video about 6 geological mysteries we have yet to solve! Hosted by: Hank Green SciShow has a spinoff podcast! It's called SciShow Tangents.
