The Thar Desert has extended in the western part of India. It is formed by ancient deposits and is a physio – graphically arid region. There are different views about the origin of Thar. Some scholars consider that the sand found in the Thar is a result of erosion and decomposition of different rocks. On the other hand, some scholars believe that there was wet climate in this part long time ago, but due to some reason, aridness kept on increasing and it turned into a desert.
Some scholars believe that long years ago, it was a fertile land and many rivers flowed through this part, but due to some disturbances, this area rose up and the flow of the rivers here was captured by the Rivers Ganga and Yamuna and so the aridity of this area increased at large, and as a result, the Desert of Thar came into existance. But a scholar Law – Toosh says that the Thar Desert was formed by the sand which was brought and deposited by the south – western strong storms.
