Information of water cycle and water conservation
Answers
Answer:
Water moves from clouds to land and back to the ocean in a never ending cycle. ... Ocean water evaporates into the atmosphere, leaving impurities behind, and moves across the earth as water vapor. Water in lakes, ponds, rivers, and streams also evaporates and joins the moisture in the atmosphere.
WATER CYCLE
The process in which water evaporates and falls on the land as rain and later flows back into the sea via rivers is called water cycle.
1) Water evaporates from hydrosphere(oceans, seas, river, lakes, ponds) with sun's heat and form clouds.
2)By the help of wind, clouds are blown over the land, where they are cooled enough to drop water as rain.
3)Rain may fall directly into the ocean also. Some water from rain and melting snow soaks into ground, but some flows in rivers and then to seas.
4) The ground water comes to surface again by springs and pumps. It is used in agriculture, industry, home. Water then evaporates into the atmosphere. It also evaporates from snow, reservoirs, ground.
5)Water vapour added by evaporation to atmosphere again form clouds.
As water flows through or over the rocks containing soluble minerals,various soluble minerals get dissolved in it and transported to distant places. Many nutrients are carried by water from parent rock to river and then to the seas. Hence these minerals are used by marine organisms.
WATER CONSERVATION
Water conservation is the use of water efficiently to decrease unnecessary water consumption.
Three ways to conserve water:
•Rainwater harvesting systems should be followed in villages, towns and cities.
•Industries should not discharge effluents directly into water bodies. These effluents should be first treated before safely disposing them.
•Efforts should be made by each individual at a personal level to conserve water. For example, taps should be closed while brushing teeth, garbage should not be dumped into water bodies and used water should be used for watering plants.
