Detailed explanation-1: -Deserts get about 250 millimeters (10 inches) of rain per year-the least amount of rain of all of the biomes.

Detailed explanation-2: -Atacama Desert surrounds the city of Arica. Some parts of this desert have not received rainfall in more than 500 years. The Andes Mountains and the Chilean Coast Range surrounds the Atacama which block moisture and rain clouds from reaching the desert.

Detailed explanation-3: -The tropical rainforest biome gets the highest precipitation or rainfall annually. Most regions get at least 200 cm to about 430 cm rain annually. Deserts and tundra get the least amount of precipitation.

Detailed explanation-4: -Deserts are arid ecosystems that receive fewer than 25 centimeters (10 inches) of precipitation a year. Death Valley, California, above, receives fewer than 5 centimeters (2 inches) of rainfall every year. However, Death Valley’s infrequent rain and extreme temperatures can impact the landscape.

Detailed explanation-5: -The desert and the nonforest biome (tundra) are the two biomes that receive the least amount of rainfall during the year. The tundra receives very little precipitation about 6-10 inches annually, mostly in the form of snow, and the desert receives less than 9.9 inches per year.
