Reasons for the formation of Indian desert

1. The Indian desert is located in the east of the Indus Plain, bordering the Indian Ocean in the south and the Himalayas in the back. In winter, controlled by subtropical high, downdraft prevails and precipitation is scarce;

2. In summer, due to the blocking of the Himalayas, it is difficult for cold air masses to move southward, and cold and warm air masses cannot meet in this area, and effective precipitation cannot be formed;

3. The climate is hot and the evaporation is greater than the precipitation;

4. The Indus Valley is an area of early human activities. Historically, the population was too dense to bear, and it gradually became desertification.
