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’m with you all on C. Wind is the main player here!

C is the best choice. Wind moves sand effectively.

I feel like A) is a trick option. Water doesn’t form dunes like that.

Definitely C! Water wouldn't create that kind of structure.

Agreed! The shape of the dune screams wind formation.

I think it's C) Deposition by wind. Looks like wind action to me.

Physical weathering isn't right either. It's about movement.

C makes sense. Look at how dunes form in deserts.

C makes the most sense, but I’m surprised it’s not more obvious!

Not so sure about that, looks more like wind to me.

Wait, could it be A) Deposition by flowing water?

I keep mixing up weathering types. Is chemical weathering really not involved here?

I practiced a similar question last week, and it was about how wind moves sand. I feel confident it's C.

I'm not entirely sure, but I remember something about how water can shape landscapes too. Could it be A?

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