Question

How are slumps and slides different?

A. Slumps are a type of sediment flow. Slides are a type of slope failure.

B. Slides are a type of sediment flow. Slumps are a type of slope failure.

C. Slumps happen very quickly. Slides happen very slowly over time.

D. Slides move sediment down pre- existing rock surfaces. Slumps carve out curves of sediment.

Answer 1

I think the answer is D. Slides move sediment down pre-existing rock surfaces. Slumps carve out curves of sediment. Sorry if wrong.

Answer 2

D. Slides move sediment down pre- existing rock surfaces. Slumps carve out curves of sediment.

Step-by-step explanation:

In a slides,the descending mass moves along a plane almost parallel to the slope of the surface. it involves moving rocks down a pre-existing rock surface

slump involve movement along a curved surface. it is known as a rotational slumping.
