Deserts are the driest places on Earth. By day, deserts maybe baking hot, but at night they can be freezing cold. There are three main types of desert. These are hot deserts, cold deserts, and coastal deserts. They all have things in common, including very little rainfall, few animals and plants, and strong winds. When people think of deserts, they usually think of sand, the tiny particles of rocks and minerals that also occur on beaches. In fact, only about 20 percent of the world’s deserts are covered in sand. Most deserts are mainly made up of rocks or gravel, while others are icy.
