Answers
Explanation:1.As the air rises,it expands and drops the temperature and subsequently,condensation takes place and cumulus clouds are formed. The 3 types of rainfall is :- Relief, conventional, frontal
Answer: Clouds are formed when water vapour , an invisible gas turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. These energetic molecules then escape from the liquid water in the form of gas.
The three different types of rainfall are:-
a) conventional rainfall-
b) orographic or relief rainfall
c) cyclonic or frontal rainfall.
Answer: Humidity is the amount of water vapour in the air. If there is a lot of water vapour in the air the humidity will be high . The higher humidity the wetter is feels outside.
Humidity plays an important role in surface life. For animal life , it is dependent on the perspiration(sweating) to regulate internal body temperature, high humidity impairs heat exchange efficiency by reducing the rate of moisture evaporation from skin surfaces.
