Five sources of water

Answer 1

Industrial Wastes

Industries often dump their byproduct (unwanted products that come during their process of production) into nearby rivers and lakes. These contaminants are usually very toxic chemicals.

Improper Drainage

After the removal of solid wastes and certain level of purification, the contaminated water is often dumped into broad rivers. But in course of time these dumping of contaminated water acts as major pollutants, usually at disposal sites.

Over use of Chemical Fertilizers

Chemical fertilizers sprayed over plants are often washed off during irrigation or by rain into rivers and lakes, contaminating them.

Thermal Pollution

Most industries want their working systems to be cooled downed in regular intervals, especially Power Plants. The naturally available water bodies tend to acts as better and free coolants. Water absorbs the heat from the systems and moves into water bodies causing change in temperature and hence threat to the living organisms there.

Answer 2

1. Rainfall: Water collected from precipitation.
2. Surface water: Water found in lakes, rivers, and streams.
3. Groundwater: Water stored beneath the Earth's surface in aquifers.
4. Glaciers and ice caps: Frozen water that melts to contribute to water sources.
5. Desalination: Process of removing salt from seawater to make it suitable for drinking and other uses.

Answer 3

Ocean water, fresh water, ground water, and rain water

Answer 4

Surface water is water that can be found on the surface of earth. Four sources of surface water includes, lakes, oceans, rivers, and streams.

Answer 5

Well rain

*****
