उत्तर १
The air in a region is dry primarily due to low moisture content. Moreover, distance from the sea, the high speed of the wind and increased rate of evaporation contribute to a decrease in the moisture holding capacity of the atmosphere.
For example, in Rajasthan, the air is dry and hot leading to the low moisture content in the air.
