Question

what is the major reason for the formation of desert
?​

Answer 1

Answer:

Desert areas distinguish themselves from other areas on the planet by the amount of rainfall they receive in a year. The stereotypical image of a sandy, windswept desert comes to mind, but deserts can be barren and rocky with no sand.

In these areas, the atmosphere has high pressure. High-pressure air forces low-pressure air–usually dry air at higher altitudes–closer to the ground. Because low-pressure air has little moisture and exists near the ground, the sun can heat it easily. This heat transfers to the ground, creating high ground temperatures. The Sahara Desert and the Kalahari Desert, both in Africa, formed as a result of low-pressure air heating the ground and evaporating groundwater.
