Detailed explanation-1: -Desert is that biome where there is very little rainfall. It can be hot like the Sahara desert and Thar desert or can be cold like Antarctica or Ladakh. In the desert area there is very less rainfall and high temperature hence climate will be hot and dry.

Detailed explanation-2: -Hot and dry desert. The four major North American deserts of this type are the Chihuahuan, Sonoran, Mojave and Great Basin. Others outside the U.S. include the Southern Asian realm, Neotropical (South and Central America), Ethiopian (Africa) and Australian.

Detailed explanation-3: -With the relative lack in moisture, there is less evaporation. There are also less clouds to reflect the sunlight away. With no evaporative cooling and a relative lack of vegetation to use the sunlight, most all of the sunlight goes into warming the ground surface. This causes very hot afternoon temperatures.

Detailed explanation-4: -The Sahara is the largest hot desert in the world, and the third largest desert behind Antarctica and the Arctic, which are both cold deserts.

Detailed explanation-5: -There are four types of deserts: subtropical deserts are hot and dry year-round; coastal deserts have cool winters and warm summers; cold winter deserts have long, dry summers and low rainfall in the winter; polar deserts are cold year-round.
