Interpretation :
The formation of cloud needs to be explained starting from water in a lake.
Concept Introduction :
Water from lake evaporates and condenses to form a cloud.

Explanation of Solution
In day time, the sunlight falls on the lake water. The water becomes hot and evaporation takes place. The water vapor being lighter goes up and condenses when gets cooled. The tiny droplets are produced which floats as cloud.
