What percentage of a desert is made up of sanddunes?
It depends on which desert! I'm living in the middle of one and it has no sand dunes at all. A desert isn't necessarily a place of hot, dry sand and sun. A desert is merely any place that has an extremely low annual rainfall. Some deserts are indeed hot and dry with rolling sand dunes, and some are indeed almost nothing but rolling sand dunes. However, most deserts are merely dry and covered in grasses and small salty bushes that require very little water to survive. Deserts can also be lush and full of life along rivers that flow through them from areas where it does rain more often (such as nearby mountains); and some of the deserts on this planet are covered in ice all year.
What are the stages of dune formation?
Sand blown loose from dry desert soil often builds up into dunes. A dune may begin to form when windblown sand is deposited in the sheltered area behind an obsticle, such as more grains accumulate. Dunes are gradually moved along by wind.
