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.

How do erosion and deposition work together to create a moraine?

A
Waves cause erosion along coastlines and deposit sand away from the shore.
B
Surface water in rivers causes erosion, carrying sediment that gets deposited near an ocean.
C
Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
D
