How much rainfall does a desert get? A desert is defined as an area that receives on average less than10 inches (250 mm) of precipitation per year. Some desert areasreceive virtually no rain at all for years.
Yet more than one billion people, one-sixth of the Earth's population, actually live in desert regions. Deserts cover more than one fifth of the Earth's land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert.Deserts are part of a wider classification of regions called drylands..thers are mountainous. Only about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain. Desert animals have adapted ways to help them keep cool and use less water.
