Question

Q. In which of the following given types of rainfall, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds?

• A.
  Convectional rainfall
• B.
  Frontal rainfall
• C.
  Orographic rainfall
• D.
  Normal rainfall

Answer 1

The correct option is A

Convectional rainfall
Explanation:

Option (a) is correct because the convectional rainfall occurs due to the thermal convection currents caused due to the heating of ground due to insolation. Convectional rainfall is prevalent in equatorial regions. In these, the warm air rises and expands then reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds.
