Here's why:

* Extreme Temperatures: Deserts experience intense solar radiation during the day, leading to scorching temperatures. However, with little cloud cover, heat escapes rapidly at night, causing significant drops in temperature.

* Very Little Rainfall: Deserts are characterized by extremely low rainfall, often receiving less than 10 inches per year. This arid climate is a defining feature of deserts.
