Which process is responsible for the formation of the sand dune pictured above?

ADeposition by flowing water

BPhysical weathering

CDeposition by wind

DChemical weathering

Show Suggested Answer

Suggested Answer: C

The formation of sand dunes, as shown in the picture, is primarily due to the process of deposition by wind. Wind transports sand and other fine particles over long distances, and when the wind speed decreases, these particles settle and accumulate, forming dunes. This process is particularly common in arid and semi-arid regions where vegetation is sparse, allowing the wind to move freely.

I think the answer might be C, deposition by wind, since dunes are usually formed by wind action.
