What is the yearly average amount of rainfall in a desert biome?

Answer 1

In the USA, the "Hot and Dry" desert biomes experiences less than 10 inches per year. However, I've spoken with more than a few desert museum-type docents, and several believe that less than four inches per year qualifies an area to be considered a desert.

There are three other types of desert to be found in the world. Their stats may vary. For more information, please see the related ink below.

Answer 2

There is very little rainfall in a desert ecosystem. Most of the precipitation in a desert comes from morning dew.

Answer 3

A desert is defined as a region that receives, on average, less than 10 inches (250 mm) of precipitation per year. Some deserts receive virtually no rain over centuries.

Answer 4

The yearly average amount of rainfall in a desert biome is typically less than 10 inches (250 mm) per year. Deserts are characterized by low precipitation levels and dry conditions.
