Cloud formation almost doesn't take place in the stratoshere because

Options

A. the high temperature of this layer does not allow the water vapour to reach this layer.
B. of the absence of convection current.
C. of the absence of dust particles and convection current.
D. All of the above

Answer

D

Explanation

Due to the absorption of highly energetic radiations, i.e., UV radiations by the stratosphere, the temperature is high when compared to the troposphere. The high temperature of the stratosphere does not allow the water vapour to reach the stratosphere due to the absence of convection current. Hence, cloud formation does not take place in the stratosphere. Cloud formation requires convection currents and also dust particles for condensation of water droplets.
