How do erosion and deposition work together to form sand dunes?

A
Waves cause erosion along coastlines and deposit sand away from the shore.
B
Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes.
C
Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions.
D
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.

landslide, slump, and deposition
D
slump, weathering, and creep
9

Which statement best describes a characteristic of deposition?

A
Sediment settles in a new place due to size, water speed, and land shape.
B
Sediment is removed from a new surface location.
C
Moving water affects where sediment travels.
D
Rocks are broken into smaller particles.
