THE DESERT. .

This lesson describes a Desert..

When we hear the word ‘Desert’ the image that come to mind is that of a vast stretch of sand with no trees or plants..

The word Desert means a place that does not get rainfall and has no vegetation..

Desert do receive rainfall, though only rarely.. .

Desert are not always flat, they can have hills, mountain and hills..

An oasis is a green island in the desert, with a spring or a well supporting life..

Desert can be hot like thar or cold like ladakh ..

9). Some Desert have almost no water.. . .

In such Desert, strong winds lift heap of sand and move them around, forming sand dunes..

These sand dunes keep shifting all the time .. .

abstract. Many people , plants and animals live in Desert..

They adapt themselves to the hot and dry conditions..

Plants and animals living in Desert can survive with less water.

For example camels don’t need to drink water every day..

abstract. They don’t sweat much and therefore they retain water in their body..

Camel can also tolerate very high body temperatures..

Smaller desert animals stay underground during the day and come out at night. They get their water from the meat of their prey..

Other desert animals obtain water from the plants and seeds they eat..

Cactus roots absorb moisture from the light, occasional rains. The cactus store water in its thick stem..

Generally, the Desert climate is dry and the temperatures very significantly between day and night ..

Since Desert do not have a layer of moisture covering the earth’s surface, the land is exposed to the harsh ray of the sun. so, it is very hot during the day and cold at night..

Like forest an oceans, desert are also a part of nature with their own beauty and importance.
