Q
What happens during convectional rainfall?
A
Occurs when the sun’s energy heats the surface of the Earth, causing water to evaporate to form water vapour.
As the air rises, it cools and condenses. This process of condensation forms clouds high in the atmosphere. If this process continues, rainfall will occur.
