Question

Describe the categories of the various source of water.

Answer 1

Sources of water can be mostly classified into two types which are:

1. Surface water: Water found on the earth’s surface is called surface water. This is sub classified into three types based on the purity of water. They are:

• Rain water: This is the purest form of water. Rain or snow which showers on the surface of the earth as a result of precipitation provides fresh water to our planet.
• River and lake water: The source of water in these water bodies is either from the rainfall or from the melting of snow on mountains.
• Sea and ocean water: Oceans and seas are huge water bodies which have millions of litres of water in it.

(b) Underground water or subsoil water: The seepage and collection of rainwater in the soil, sand and rocks under the ground is called underground water which can be brought to the surface in the form of springs or by drilling in wells.
