5.) Write a note about the following.
(a) Evaporation
Ans:
Evaporation is the process in which water on the earth surface converted into water vapour due to sun heat.
(b) Condensation
Ans:
The water vapour formed due to evaporation is light weight than air. It easily goes in atmosphere. Due to increase in height these water vapour gets cooled and form water droplet this process s called as “condensation”
(c) The water cycle
Ans:
Evaporation and condensation process continuously going on and rainfall happens. This makes a cycle called as “water cycle”
