A layer of coarse pebbles and gravel formed when wind removes finer material is called?

• A. Desert pavement
• B. Carbon Sink
• C. Glacier
• D. Soil Profile

Answer: (A)

This is about how desert surfaces form through wind erosion. When wind blows away the finer particles—sand, silt, and dust—the remaining larger grains, like pebbles and gravel, pack together on the surface. This produces a hard, smooth layer known as desert pavement. It happens because the fine material is removed (deflation), leaving behind the coarser material that stays in place and creates that armored surface. The other terms don’t fit this description: a carbon sink is a place where carbon is stored, not a surface of stones; a glacier is a large body of moving ice; and a soil profile is the vertical layering of soil beneath the surface. So the layer formed by wind-removing finer material is desert pavement.
