write short note on indian desert

TheThar Desert(Rajasthani: ,Hindi: ²,Punjabi:¨¨¨ ¨¨¨©‚¨¨²,Urdu:ØحرØÛ’ÙŽ تÚر‎,Sindhi:Ùر ريÚستØÙ†) also known as theGreat Indian Desert) is a large, arid region in the northwestern part of theIndian subcontinentand forms a natural boundary running along the border between India andPakistan. With an area of more than 200,000 km²(77,000 sq mi), within the Indian state ofRajasthan, covering the districts ofJaisalmer,Barmer,BikanerandJodhpur, and some region of the states ofPunjab,HaryanaandGujarat.it is the world 's18th largest subtropical desert.Thar Desert extends from the Sutlej River, surrounded by theAravalli Rangeson the east, on the south by the salt marsh known as theGreat Rann of Kutch(parts of which are sometimes included in the Thar), and on the west by theIndus River. Its boundary to the large thorny steppe to the north is ill-defined.The origin of the Thar Desert is a controversial subject. Some consider it to be 4000 to 10,000 years old, whereas others state that aridity started in this region much earlier.

The state of Rajasthan lies in the south-western part of the Northern Plains. The Aravalli Hills divided it into two parts. The western part is a big desert and the land is covered with sand. This area has hardly any vegetation and is called the India desert or the Thar Desert.

The Indian desert extends from Aravalli hills to the border of Pakistan in the west, and from Kachchh in the south-west to the border of Haryana. The Indian desert is partly sandy and partly rocky. In many places, there are small hillocks of sand. These are called dunes. Dust storms are very common in desert.

Strong can easily move the sand from one place to another, and thus the sand dunes keep shifting all the time. In the desert areas, the summer season is very hot and the winters are very cold. After the sun sets, the sand cools down quickly and thus the nights are very cold. There is hardly any rainfall.

There are no permanent rivers only some small streams which are usually dry. They start flowing only when it rains. Vegetation is limited to scattered, thorny bushes. It is difficult to build rods and railway lines in a desert. Camels are the chief mode of transportation. A camel can live for days without food and water. It is thus very useful in a desert. There is always a shortage of water. At a few places, the underground water comes up to the surface and forms big pools. Such a place is called an oasis. Some trees like date palms, kikar, babul and grass grow in the oasis. Small villages also develop around an oasis.

The soil in the desert is quite fertile, but it is difficult to grow crops because there is little or no water. The situation is now changing. The government is making serious efforts to improve the life of the people in the desert areas. Water has been brought to the desert from the Satluj River through the Indira Gandhi canal is used for irrigation.

A big farm has already been developed at Suratgarh in Rajasthan. The blooming of the desert has begun.

Deserts are generally formed because of shortage of water in a place. But man is also responsible for creating desert. If we destroy the forests and if we allow the cattle, sheep and goats to graze the grasslands faster than they can produce fresh grass, the land becomes a desert.

Cutting down of forests and overgrazing of grassland must be controlled. We can do it by planting trees and shrubs and keeping the land covered with grasses. We can grow many types of crops by using the limited water resources properly. This will help in improving the life of the people in the desert areas.

Great Indian Desert can be characterised by the following features:

• It is located on the north western frontiers of India, also known as the khar desert
• The rate of precipitation is the least
• Has very extreme temperatures during day or night.

The Indian Desert

The Indian desert lies towards the western margins of the Aravali Hills. This region gets scanty rainfall which is less than 150 mm in a year. Hence they climate is arid and vegetation is scanty. Luni is the only large river but some streams appear during rainy season. Crescent-shaped dunes (barchans) abound in this area.

The Thar Desert, also known as the Great Indian Desert, is a large, arid region in the northwestern part of the Indian subcontinent and forms a natural boundary running along the border between India and Pakistan. With an area of more than 200,000 km2 (77,000 sq mi),it is the world's 9th largest subtropical desert.It lies mostly in the Indian State of Rajasthan, and extends into the southern portion of Haryana and Punjab states and into northern Gujarat state. In Pakistan, the desert covers eastern Sindh province and the southeastern portion of Pakistan's Punjab province. The Cholistan Desert adjoins the Thar desert spreading into Pakistani Punjab province.

The Great Indian Desert lies to the South-west of the fertile Northern Plain or the Gangetic Plain. It is also called the Thar Desert. The Aravali Hills divide Rajasthan into two parts. The Western part of Rajasthan is the Great Indian Desert. Its soil is composed of sand, hard rocks and sand dunes.

In the given map you find that the Great Indian Desert extends from the Aravalis in the East to Pakistan in the West. It touches the boundaries of Punjab and Haryana in the North and the North­east and Runn of Kutch in Gujarat in the South. Actually the Indian Desert is a part of a very big desert. The Thar Desert which extends to Sindh in Pakistan and beyond Pakistan to Arabia.

The Great Indian Desert is a vast stretch of sand and sand dunes which is about 500 km. long and 200 to 250 km. wide. Sand dunes are mounds piled up of sand. The strong winds carry away these dunes to other places and they keep on changing their places.

A desert is a place that has few, or sometimes even no, life forms. Sometimes life forms adapt to living in deserts, but conditions tend to be extreme, and survival is challenging.

Some deserts can be visited but not lived in. Some deserts are so inhospitable that life as we know it cannot survive in them at all.

In terms of rainfall, areas that receive less than ten inches of rain a year are considered to be deserts.

Some deserts receive only three or four inches of rain a year. A few places do not receive any rain at all.

When we think about deserts, we think about limiting factors.

on earth, liquid water is necessary for life. Some life forms survive periods when water is not available by becoming spores or seeds, or by becoming dormant (hibernation or estivation). Some plants can survive for many years as seeds. Insects and unicellular life forms can also wait out drought. Sooner or later, however, liquid water is necessary. Survival is essential, but it is not all of life. Without growth and reproduction, life is on hold, not progressing.

Salinity can also interfere with an organism's use of water. Fresh water fish cannot live in the ocean, and land plants watered with sea water will die. The excess salt in briny water pulls water out of the organism and dehydrates it. If you put a salt water fish in fresh water it will die, too, because the organism will retain too much water in its cells.

Sunlight: is the ultimate source of most of the energy used by living things on earth. Plants use sunlight for photosynthesis. Lack of light in caves and under deep water make these environments unsuitable for photosynthesizing plants.
