_________ is a sand hill that has a crescent-moon shape.Question 16Answera.Sand duneb.Lagoonc.Barchand.Loess deposit
Solution
The sand hill that has a crescent-moon shape is called a Barchan.
Here's why:
A barchan, or barchan dune, is a crescent-shaped dune that forms in desert or coastal areas. The shape of the dune is created by the action of wind blowing from one direction. The "horns" or "arms" of the crescent point downwind.
Sand dunes are hills of sand built by wind or water flow, but they can come in many shapes, not just crescent. Lagoons and loess deposits are not related to sand hills.
So, the correct answer is c. Barchan.
