Answer 2

A geologist is studying a sand dune. The sand dune was formed as wind deposited sand against an obstruction deflation.

What causes the sand dune?

Sand dunes are created whilst wind deposits sand on pinnacle of every different till a small mound begins offevolved to form. Once that first mound forms, sand piles up at the windward facet increasingly till the brink of the dune collapses beneathneath its very own weight.

1. In geology, Deflation may be described because the procedure with the aid of using which loose, mild weight and small debris fashioned with the aid of using the weathering of erosion of pinnacle-soil of the earth crust or the dirt and sand debris are carried from one vicinity to some other with the aid of using the movement of wind.
2. When those debris hit or strike an obstruction like a mountain or hill they crumple at the floor.
3. Gradually with time, several such debris crumple and collect at the floor after hanging an obstruction and finally bring about the formation of a sand dune.
