(i)
Things remain damp and wet, and take longer time to dry when the
atmosphere around them is damp and wet. Humidity is the amount of
moisture or water vapour present in air at any moment in time. On a
humid day, the air is full of water vapour. As the air gets warmer,
its capacity to hold the water vapour increases. As a result,
conditions become more and more humid. Hence, wet clothes take longer
time to dry on a humid day.
(ii)
Insolation refers to the incoming solar
radiations intercepted by the Earth. The amount of sunlight received
by the regions close to the Equator is greater than the amount of
sunlight received by the regions close to the Poles. This is because
of the tilt of the Earth’s axis. As a result of this tilt, the
incoming solar radiations cover a greater area at the Equator than at
the Poles.
