Question

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

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

Answer 1

Answer:

Erosion and deposition work together to form sand dunes is stated below.

Explanation:

Dust storm are more common in dry climates. The soil is dried out and dusty. Plants may be few and far between. Dry, bare soil is more easily blown away by the wind than wetter soil or soil held in place by plant roots.

when the wind deposits sand, it forms small hills of sand. These hills are called sand dunes. For sand dunes to form, there must be plenty of sand and wind. Sand dunes are found mainly in deserts and on beaches.Sand dunes form where the wind deposits sand. (A) Desert sand dunes. (B) sand dunes line many beaches like this one in Australia.

Answer 2

Answer:

Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.

Explanation:

• Deposition is mainly caused by erosion and results in the deposit of sediment on a landform (landmass), which can make building foundations stronger and more resistant to stress.
• Sand dunes are formed primarily as a result of the combined effects of erosion and deposition. Sand dunes are formed when sands are removed off rocks by deflation, causing additional sand to accumulate.
• Furthermore, powerful winds pick up the collected sands and deposit them in another spot, sometimes against a barrier.
• As glaciers melt, they bring debris that is deposited in a thick layer, causing erosion.
