Detailed explanation-1: -The most obvious climatic feature of this climate is that potential evaporation and transpiration exceed precipitation. These climates extend from 20°-35° North and South of the equator and in large continental regions of the mid-latitudes often surrounded by mountains.

Detailed explanation-2: -Regions lying within the dry climate group occur where precipitation is low. There are two dry climate types: arid and semiarid. Most arid climates receive 10 to 30 centimeters (four to 12 inches) of rain each year, and semiarid climates receive enough to support extensive grasslands.

Detailed explanation-3: -The regions of highest rainfall are found in the equatorial zone and the monsoon area of Southeast Asia. Middle latitudes receive moderate amounts of precipitation, but little falls in the desert regions of the subtropics and around the poles.

Detailed explanation-4: -Dry Valleys, Antarctica The valleys have extremely low humidity and almost no ice or snow cover the largest ice-free region on the continent.

Detailed explanation-5: -The Indian Desert is located to the north-west of the Aravali hills lies the Great Indian Desert. This region receives low rainfall below 150 mm per year; hence, it has arid climate with low vegetation cover.
