Answers
Answer:
The forebodings are ominous. Like a menacing leviathan the Great Indian Desert is crawling towards other parts of north India, including Delhi. There have been unmistakable signs of this phenomenon: droughts and famine are becoming more frequent.
In fact, this century's worst famines were recorded in the past two years. Never before have eight droughts occurred in a decade, like from 1978-1988. The Palam observatory in Delhi recorded 153 mm of rain this year, which is 487 mm less than the normal. Increasingly, the capital and nearby regions are being shrouded by dust.
The reason: the once-green 692-km-long Aravalli ranges, stretching from the Delhi ridge to Banaskantha in north Gujarat, have been denuded of their forest cover in a short span of 40 years. Worse, the core of the Thar desert region has shifted from the central to the northern fringe of the Aravallis and is now centred in Delhi. The Aravallis, the last bastion between the encroaching desert and the north Indian bread basket, is gradually withering away.

Answer:
Thar Desert, also called Great Indian Desert, arid region of rolling sand hills on the Indian subcontinent. It is located partly in Rajasthan state, northwestern India, and partly in Punjab and Sindh (Sind) provinces, eastern Pakistan.This is because the rock and sand absorb heat during the day and releases it at night. There may also be an extreme variation between warm and cool seasons, including extreme winds and storms due to the mixing of cold and warm air. Deserts are vitally important to the planetary ecosystem.
