Question

What are known as Deflation Hollows?

Answer 1

Deflation Hollows are depressions or hollows formed by the action of wind erosion. In these areas, wind removes loose materials, like sand and pebbles, from the surface, resulting in the lowering of the land. These hollows can be significant in desert areas where the wind is strong enough to carry away finer dust and sand. An example of a deflation hollow is the Qattara Depression in the Sahara Desert, which is nearly 450 feet below sea level.
