                                                               The Sahara Desert

     The hottest place in the world is the Sahara Desert in Africa. But there are deserts in many other places:

in America, in Asia and in Australia. In 1917 the temperature in Death Valley, in the United States, was over

48℃ every day for six weeks. That's very hot!

     But deserts are not always hot. After dark, desserts are very cold.

     Not many animals and plants can live in a desert,because it doesn't rain very often. But one animal likes

the desert-the camel. It has big feet to walk on the sand. It can live for a long time without water. Sometimes

it doesn't drink anything for weeks-so it gets very thirsty! When it finds water it can drink 100 liters at a time.
