3 Temperature The hot desert is a land of extremes: extreme heat and extreme dryness; sudden flash floods and cold nights. Because deserts are such a harsh environment, deserts often have names likes "Death Valley," "the empty quarter," and "the place from where there is no return." THE DESERT IS THE HOTTEST BIOME!!!

4 Temperature Everyone knows that during the day many deserts are hot, very hot. Temperatures in excess of 100 degrees Fahrenheit are not uncommon. Yet at night, the same deserts can have temperatures fall into the 40’s or 50’s.

5 Precipitation Deserts are usually very, very dry. Even the wettest deserts get less than ten inches of precipitation a year. Deserts receive the least amount of rainfall of all the other biomes.-Less than 10 inches per year

Desert plants have two main adaptations:  Ability to collect and store water  Features that reduce water loss like waxy leaves.

The Sahara is one of the hottest places on Earth. Even though temperatures there may rise to 136 F (57.7 C), its dryness, not heat, that makes a place like the Sahara a desert. It receives less than 3 inches of rain per year!
