EVERYDAY SCIENCE

Detailed explanation-1: -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. Deserts are also characterized by extreme temperatures.

Detailed explanation-2: -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. In all deserts, there is little water available for plants and other organisms.

Detailed explanation-3: -Due to the desert area, trees are very rare and natural water sources are few. Greenery is the primary basis to attract rain, which is not there, hence clouds passing through and not raining.

Detailed explanation-4: -Arid environment. Extreme temperatures. High wind velocity. Sparsity of cloud cover. Absence of water vapour in air.

Detailed explanation-5: -A High temperature. B Low rainfall. C Scanty vegetation. In deserts, water evaporates quickly due to high temperature and sunny conditions during the day. The rainfall is very low and does not support the growth of tall trees or grasslands. For the same reason, there is very less humidity in deserts.
