the heat of
the sun warms the surface and the air
above it. As warm air is lighter than
cold air, it rises, carrying moisture
with it.
The rising warm air meets cool air
and the moisture, or water vapour,
in the atmosphere condenses to form
water droplets. Condensation releases
energy. The energy makes the rising
air warmer than the surrounding air,
because of which the air keeps rising.
As more and more moisture-laden air
keeps rising, it forms cumulonimbus
clouds. Such clouds are accompanied
by thunder and lightning. They are
also called thunderclouds.
Warm air rises and condenses
to form cumulonimbus clouds.
