The correct option is C C. 2 & 3 only
87. C
Insolation is the incoming solar energy intercepted by the earth. The amount of insolation decreases from the equator towards the poles. As we go up the layers of atmosphere, the pressure falls rapidly. The air pressure is highest at sea level and decreases with height. Horizontally the distribution of air pressure is influenced by temperature of air at a given place. In areas where temperature is high the air gets heated and rises. This creates a low-pressure area. Low pressure is associated with cloudy skies and wet weather.
