Which biome is characterized by low rainfall and extreme temperatures?

The desert biome is defined by its low levels of rainfall, typically receiving less than 10 inches annually. This scarcity of water leads to extreme temperature fluctuations; deserts can experience incredibly high temperatures during the day and drop to significantly lower temperatures at night. The lack of moisture contributes to the arid conditions that are a hallmark of deserts, which can be found in various geographical locations around the world, such as the Sahara and the Mojave.

In contrast, grasslands are characterized by more moderate rainfall and support a variety of grasses and occasional trees and shrubs. The tundra biome experiences cold temperatures, but its challenges stem from permafrost and limited vegetation rather than extreme heat. Taiga, or boreal forest, has a different climate, typically featuring significant rainfall, particularly in the summer, and is dominated by coniferous forests. All these other biomes do not share the same extreme temperature conditions and low rainfall characteristics that distinctly define the desert biome.
