studiot, Thank you very much for this detailed response - this is extremely helpful. I'm an honors earth science student, so while I find the subject fascinating, I'm just beginning my studies and I'm beginning to question my teachers methods, as the material on that sheet was not covered during our classroom sessions. I will update the thread when my lab is returned. I really appreciate everyone taking time to respond - it's very much appreciated !

It's clear that in the last image the agent causing erosion is water. I suspect wind in the second image and perhaps glacier or ice in the first ?

I would think that resistant layers would erode slower - simply because of the word "resistant". The last picture appears to show water, which I imagine would expedite the erosion of any layer. In the last image, it appears that the top layer is most resistant, but it's definitely not clear to me. I appreciate the responses.

Hi - I'm struggling to understand the attached question from a take home lab. If anyone has suggestions, clarification, or explanation - I would greatly appreciate it. Thank you
