Deserts

When we hear the word DESERT, the first thing that comes to our mind is scarcity of water.

Desert is a region of very low rainfall and very less vegetation.

They have extremes of temperature that is very hot and very cold.

Hence depending on the temperatures there can be two types of deserts HOT or COLD deserts.

Let us see life in hot deserts by taking the example of Sahara.

The Sahara Desert is the world's largest desert covering over 8.54 million square kilometers.

It touches 11 countries namely Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia, and Western Sahara.

When we think of desert the only thing we can imagine is sand.

But this is not the case with Sahara. Sahara desert has gravel plains and plateaus too.

Gravel plains are a mixture of rock fragments.

Now let us see the climate of Sahara.

It is extremely hot and has a short rainy season.

The sky is cloudless and clear, there is no sign of moisture.

Days are very hot, reaching about 50-degree Celsius, making everything around very hot.

Nights, on the other hand, are freezing cold with temperatures nearing 0 degrees Celsius.

Vegetation and wildlife of Sahara desert

Cactus, date, palms, and acacia are found in the Sahara desert.

At some places in deserts, underground water comes to the surface. This is called oasis.

Trees like date palms grow around that water forming a green island.

Animals like Camels, jackals, foxes, snakes and scorpions can be seen here.

Life of People In Sahara Deserts

The main types of tribes who live here are: Bedouins and Tuaregs.

These groups are nomadic tribes rearing livestock such as goats, sheep, camels, and horses.

These animals provide valuable resources like milk, food, leather and hair.

People here wear heavy clothing to protect them against dust storms and hot winds.

Oasis in Sahara and Nile Valley in Egypt support settled population. Crops like rice, wheat barley are grown here.

Resources Of Desert

Oil, a product in great demand is found in regions of Algeria, Goshen, Libya, and Egypt.

Other important minerals found here are iron, phosphorus, manganese and uranium.

Recently the landscape is undergoing several changes.

Big buildings are being constructed.

Superhighways and trucks are replacing camels paths.

Tuaregs act as guides to foreign tourists and many nomadic communities are taking city life.
