INTRODUCTION

ateris a chemical substance with the chemical formula H2O. Its molecule contains one oxygen and

two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on

Earth with its solidstate, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state

near hydrophilic surfaces.[1][2]

Water covers 70.9% of the Earth's surface,[3] and is vital for all known forms of life.[4] On Earth, it is found mostly in

oceans and other large water bodies, with 1.6% of water below ground in aquifers and 0.001% in

the air as vapor, clouds(formed of solid and liquid water particles suspended in air), and precipitation.[5] Oceans hold

97% of surface water, glaciers and polar ice caps 2.4%, and other land surface water such

as rivers, lakes and ponds 0.6%. A very small amount of the Earth's water is contained within biological bodies and

manufactured products.

Water on Earth moves continually through a cycle of evaporation or transpiration (evapotranspiration), precipitation,

and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land.

Clean drinking water is essential to humans and other lifeforms. Access to safe drinking water has improved steadily

and substantially over the last decades in almost every part of the world.[6][7] There is a clear correlation between

access to safe water and GDP per capita.[8] However, some observers have estimated that by 2025 more than half of

the world population will be facing water-based vulnerability.[9] A recent report (November 2009) suggests that by 2030,

in some developing regions of the world, water demand will exceed supply by 50%.[10] Water plays an important role in

the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial

cooling and transportation. Approximately 70% of freshwater is consumed by agriculture.[11]

CONCLUSION

we need to use water more sparingly.

here are some ways how to save water:

Turn off the tap when you aren't using the water.

You don't need the water on full blast

To get hot water quicker (for showers etc) just turn on the hot water and wait

Wash your plates together, not individuallycapture water to water the plants

Put a bucket (or similar) in the shower and collect the water that is 'wasted' when you wait

for it to heat up. Move the bucket away afterwards, otherwise you might get soap in it.

Collect the water you use fro m washing the vegetables - don't just let it go down the drain.

Collect the water from your washing machine. The first discharge may bit a bit soapy, but thesecond is usually quite clean. 3L milk/juice bottles work very well for this.

AREA OF QUESTIONNAIRE

Roughly 70 percent of an adults body is made up of water.

The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same

water that existed on the earth millions of years ago is still present today.

The total amount of water on the earth is about 326 million cubic miles of water.

Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable

water is found in groundwater aquifers, rivers, and freshwater lakes.
