Why do deserts have less amount of water?

Deserts have less water primarily due to their low precipitation levels, often receiving less than 10 inches of rain annually. This scarcity is caused by factors such as high evaporation rates, which exceed precipitation, and geographical features that block moisture-laden air from reaching the region. Additionally, deserts often lie in rain shadows or are located in areas of high pressure, further reducing rainfall. These conditions create an arid environment, resulting in the limited availability of water.
