Environmental Balance — EVS STD 5 — Question

Our earth is covered with water bodies. The heat of the sun evaporates the water from the water bodies like sea, lake, ponds stveanes of rivers and also the water which has percolated beneath the soil. This evaporated water vapour is light, so it moves up into the higher and cooler atmosphere to form fine drops of water which float.

These smaller drops form clouds. They later join together to form big and heavy drops; which fall down as rain. The rain water goes back to the water bodies, thus the process of condensation, evaporation and rainfall continue to form a water cycle.
