In the desert regions, both tropical and temperate, both high interment basins and low open deserts the intense process of erosion as well as deposition or deflation cause the leveling of the ground. On the mountain, ward margins there may be pediments.
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.
The Thar Desert or the Great Indian Desert has an extreme type of climate. In summer it is very hot in the day while the nights are cooler. In winter the days are warmer and the nights are very chilly.
Desert animals are adapted in such a way that they can withstand heat and water scarcity. Desert rats and snakes dig holes and burrows in the sand and live inside them during daytime. At nigh when the surroundings get cooler, they come out in search of food, and are, therefore, nocturnal in habit.
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.
