Question

aim:
date:
erosion & deposition by mass movement (gravity)

• how does gravity erode and deposit sediments?

○ mass movement: downhill movement of rock or sediment due to.
gradual downhill movement of soil
rapid downslope flow of debris
downward flow of fine particles (mud) and large amounts of water
rapid falling of pieces of rock from a cliff or steep slope

• sediments eroded by gravity are:

○
○
✓ checkpoint: the diagram below shows the surface features of a landscape.

1. based on the features shown, which erosional agent had the greatest effect on tree growth and the structures that humans have built on this landscape?

a. running water
b. moving ice
c. prevailing wind
d. mass movement

Explanation:

The question is about identifying the erosional agent that affects tree growth and human - built structures. Mass movement (gravity - driven downhill movement of rock/sediment) is relevant here. Running water (A) typically creates features like rivers and valleys. Moving ice (B) forms glacial features. Prevailing wind (C) causes wind - eroded landforms like sand dunes. Mass movement (D) directly impacts slopes where trees grow and human structures are built, as it can cause landslides, etc.

Answer:

D. mass movement
