alukav5142 [94]

Answer:

Explanation:

The wind is the primary agent that moves the sediments and creates sand dunes in the deserts. When the wind starts to slow down it loses its power to carry the sediments so it starts to deposit them. As it does, a hill of sand is starting to form, called a sand dune. The wind will constantly be bringing new sediments, and the windward side is the one that gets them, while the leeward side doesn't. This results in the windward side to be much larger, but also to have much lower angle of fall, while the leeward side is having a very steep slope as it is constantly building on the top, but not the rest of it.
