The desert is the hottest biome on earth. However, the desert is also a land of extremes. It can be over 100 degrees Fahrenheit during the day but below 32 degrees at night. This change is because deserts are bare. There is little protection to keep them from heating up in the sun and cooling off when the sun disappears at night.

The amount of rainfall also varies. Though there is little rain in a desert, and when it does rain, it pours. Violent rainstorms can cause flash floods in the desert. After a storm, the desert may not see any rain for weeks or months.
