There are few areas of the earth where no rain falls for years. Such areas are dry, sandy and very hot. We call them desert. The Sahara, the Arabian desert and the Libyan desert are famous deserts of the world.
Travelling in a desert is very difficult and dangerous.
The sand there is so deep, the wheels of vehicles get sunk in it. The only way to travel in a desert is to ride a camel. Its flat feet do not get sunk and, it can travel for days with no water. Merchants cross great deserts in camel caravans.
The camels carry the people’s food, goods, water and other items on their back.
There are springs of water in few places in a desert. People inhabit them, grow date palms, fruit and vegetable there. These places are called oases.
