Saline water is not fit for drinking.
Ocean contains most of the saline water.
Saline water is used in gargling as it prevents inflammation. It also helps in killing weeds.

Evaporation is a process in which liquid state changes into a gaseous state due to an increase in temperature or an increase in Pressure.

Condensation is a process in which gaseous forms turns in liquid form.
This happens when the air gets cooler.
Water droplets clump together to form a cloud.
It so happens that many droplets of water come together to form larger sized drops of water.

Precipitation is water that falls in any form like rain, snow from the sky to the earth.

Water Cycle:

The water cycle consist of 3 main processes – Evaporation , condensation and Precipitation.

The water cycle begins with evaporation where the water on the earth surface turns into vapor
As water turns into vapor it rises up in the atmosphere and due to high altitudes the water changes into water droplets because of low temperature.
The small water droplets come together and form clouds.
Now when the air cannot hold any more water , it precipitates that means the water droplets fall down as rain.
After raining, some of the water is absorbed by the soil.
The roots of the plant absorb the water and it is received by the leaves where it is used for photosynthesis.
The extra water is moved out of the leaves through small pores(stomata) as water vapor.

It is the method by which we can use water efficiently.
It helps us to reduce the waste of water.
we can stop taking bath from showers , as it consumes a lot of water.
If you are washing dishes then close the tap while using the soap.

While brushing your teeth , don’t let the tap running.

Rainwater harvesting is the collection and storage of rain for later use rather than allowing it to get wasted.
The frequency, quantity and the quality of the rainfall play a vital role in the amount of water harvested.

It costs less.
Promotes both water and energy conservation
It is easy to operate.
It reduces soil erosion, flooding, and pollution of surface water with fertilizers, pesticides etc..
It is an excellent source of water for irrigation with no chemicals and free from minerals.

70% of the human brain consist of water.
Two glasses of water are required to produce each page of a book.
80% of all illness in the developing world is water related.
