<h3>
What is a dune?</h3>
Dunes are wind deposits, formations that are typical of deserts.
Dunes are orientated according to the direction and speed of winds and the presence of loose material and vegetation. Strong winds transport sand until it collides with an object or obstacle, where it is deposited, creating a new dune.
Dunes are very dynamic formations that are constantly, being remodeled by the direction and strength of the winds. They always have a soft slope (windward side) and a sharp one (leeward side).
- The windward side faces the direction where the wind is coming from and is the product of the wind erosion on the same dune.
- The opposite leeward side is protected from the wind and is the deposition place, where the wind losses strength and the carrying material falls, depositing on this side of the dune.
The correct option is B. windward and leeward.
