Q.

In earth atmosphere, which of the following continuously decreases with height?

Explanation:

ANS. (C) 
The relative humidity continuously decreases with height in the troposphere and is close to zero in the stratosphere. Both temperature and wind velocity show variable pattern; they decrease or increase with change in altitude. However, pressure decreases continuously with increasing height due to the reduction of the mass of overlying air. As a general rule, a height change of 10 m equals a pressure change of about 1 Mn. Pressure changes much more rapidly with height than with horizontal distance.
