A
how little rain it gets
B
how tall the trees are
C
how blue the lakes are
D
how much rain it gets
Explanation: 

Detailed explanation-1: -One thing all deserts have in common is that they are arid, or dry. Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall.

Detailed explanation-2: -Generally speaking, the Sonoran Desert averages only three to fifteen inches (76 to 400 mm) of rain a year. In the Arizona Upland subdivision of the Sonoran Desert, rain falls about equally in two rainy seasonsa winter one in December and January, and a summer one in July through early September.

Detailed explanation-3: -Deserts are characterized by low humidity (air moisture), low annual rainfall, and an overall moisture deficit, meaning the rate of evaporation exceeds the rate of rainfall on average.

Detailed explanation-4: -If rain falls it stays dry in deserts because the sand absorbs the water.
