What are deserts?

ANY LARGE REGION WHERE THE ANNUAL RAINFALL IS LESS THAN 10 INCHES (250mm) is a desert. This means that deserts have almost no water. Deserts are usually windy, but not necessarily hot, rocky and sandy, which they usually are. Like the Gobi desert, the temperature there are under freezing for 6 months of every year! But hot deserts have an unbearable climate, with approximately 40 degrees Celcius in the day, the temperature will drop to freezing point at night! Apart from the sudden change of the temperature, in parts like African and South American deserts, with almost no rain for several years, then a sudden storm may come, bringing a flash flood! Yet surprisingly, all the living things in the deserts have already adapted to these weird conditions and manage to survive healthily there.
