how is the aravali range responsible for occurance of thar desert
Answers
Answer:
The Thar Desert, also known as the Great Indian Desert, is located in the north-western part of the Indian subcontinent, to the west of the Aravalli Mountain Range. This desert comprises portions of the Indian states of Gujarat, Rajasthan and Punjab. The Indus River lies west of the Thar Desert. The Thar Desert is the seventh largest desert in the world, comprising a total area of close to 210,000 square kilometers. The desert has a volatile climate, with temperatures exceeding 50°C in the summer and dropping to around 0°C in the winter. Only about 10 percent of the area is made up of sand dunes, while the rest of the geography includes rock formations, salt lake bottoms and fixed dune areas.
The air around the Tropics of Capricorn* and Cancer* is dry. This is a zone of high air pressure where the air sinks. Air at the equator rises and cools - condensation then forms rain. The air then moves north and south of the equator until it gets to about 30° north and south of the equator, where it begins to sink. This air is dry and no condensation can form, so there is no rain. This is known as the Hadley Cell. The image below shows how air moves around the atmosphere near the equator and tropics.
