Answer 2

Answer:

"Mound of sand" deposited by "wind action" in desert is called "sand dunes".

Explanation:

A sand dune can be described as a "small mound or ridge" of hill formed out of sand. Sand dunes are generally observed to be formed in deserts, sometimes they are also formed on beaches.  

These sand dunes are formed when a high-speed wind blows the sand, but then encounters a "sheltered area" behind an obstacle. The dunes grow in size, when the grains of sand keep on accumulating.  The sand dunes always have a "windward side" and a "leeward side".
