It may be too hot or too cold. We have seen that water means life to plants, animals and people. It is difficult for anyone to live in places where there is no water to drink, where there is no grass for their cattle to feed on and where there is no water to help the corps to grow. Slide 4: We will now learn about the places the places in the world where people have learned to cope with extreme harsh temperatures; in some places as hot as fire and as cold as ice. These are the desert areas of the world. These are characterized by low rainfall, scanty vegetation and extreme temperature. Depending on the temperatures then can be hot deserts or cold deserts. The people inhabits these lands whenever little water is available to practice agriculture. Types of Deserts : The Cold Deserts – Ladakh Types of Deserts The Hot Deserts – Sahara The Hot Desert – Sahara : The Hot Desert – Sahara Sahara Desert Covering a large Part of North Africa.

The air in this altitudes so thin that the heat of the sun can be felt intensely. The day temperature in summer are just above 0 degree centigrade. It is freezing night temperature well below 30 degree centigrade . It is freezing night temperature may remain below 40 degree centigrade for most of the time. Slide 12: Flora and fauna Due to the high aridity, the vegetation is sparse. There are scanty patches of grasses and shrubs for animal to graze Groves of willows and poplars are seen in the valleys.
