The Importance of WATER
Essential to life, a person’ s survival depends on drinking water.

Water covers more than 70% of the Earth, only 1% of the Earth’s water is available as a source of drinking.

The freezing point of water is 0 C (32 F), the boiling point is 100 C (212 F).

Water makes up 50 to 90 percent of the weight of living things.

Occurrence of WATER

Water is the only substance that occurs in all three states of matter: solid, liquid, and gas. As a solid, ice, it forms glaciers, frozen lakes and rivers, snow, hail, and frost. It is liquid as rain and dew, and it covers three-quarters of the earth’s surface in swamps, lakes, rivers, and oceans. Water also occurs beneath the earth’s surface as a vast groundwater reservoir. As gas, or water vapor, it occurs as fog, steam, and clouds.
