a debris flow
If you are considering a home site, what is one pretty sure evidence of possible landslides affecting the property?
A history of previous mass wasting events in the area

Which of the following is a slow moving form of mass wasting?

A debris flow is mainly coarse-grained rock fragments, while an earth flow is mostly fine-grained sediment particles.
What do chemical and detrital sedimentary rocks have in common?
Both involve water in their formation
What is the correlation between surface area and rate of weathering?
The greater the surface area, the more the rock is exposed so the faster the weathering.
