Define water cycle and evaporation. |
|
Answer» a) Water cycle: The process of water evaporating from the seas, forming clouds in the sky, coming down as rain and flowing down the slopes on land in the form of rivers and finally joining the sea is called the water cycle. b) Evaporation: The change of water into vapour is known as evaporation. The process in which water vapour changes into water is called condensation. Clouds are tiny droplets of water hanging in the air above. |
