what is the extent of the thar desert
Thar Desert The Thar Desert, also known as the Great Indian Desert, is a large, arid region in the northwestern part of the Indian subcontinent that forms a natural boundary between India and Pakistan. It is the world's 17th largest desert, and the world's 9th largest subtropical desert.[1] About 75% of the Thar Desert is in India, and the remaining 25% is in Pakistan.[2] In India, it covers about 320,000 km2 (120,000 sq mi), forming approximately 10% of the total geographic area of India. More than 60% of the desert lies in the state of Rajasthan and extends into Gujarat, Punjab, and Haryana.[3] This desert comprises a very dry part, the Marusthali region in the west, and a semidesert region in the east with fewer sand dunes and slightly more precipitation.[4]
Atacama Desert Geographically, the aridity of the Atacama is explained by it being situated between two mountain chains (the Andes and the Chilean Coast Range) of sufficient height to prevent moisture advection from either the Pacific or the Atlantic Oceans, a two-sided rain shadow.[8]
