water conservation,water a wonder liquid

4. Water is 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 ambition conditions but it often co-exists on Earth with
its solid state , ice, and gaseous state, water vapors or steam.
Water covers 70.9% of the earths surface[and is vital for all known forms
of life. 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's
, clouds (formed of solid and liquid water particles suspended in
air), and presipitation.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.

15. All water pollution happens in one of two
ways: via non-point or point systems. Non-point
pollution comes from indirect sources, like
agricultural runoff, mining waste, paved
roads, and industrial activity. It's impossible
to trace the original polluter in these
cases, but toxic chemicals and compounds make
their way into the water system just the
same—through rainwater drainage, melting
snow, and running rivers.

17. This may not seem like such a bad thing—
after all, hot water and cold water even out
eventually, right? Right—but until
then, discharging hot water while cooling
power plants means changing the
temperature of the water source, which can
encourage the species density to change and
alter the biology of the water. Thermal
pollution, then, can be just as damaging as
bacterial or sediment pollution.

18. Eutrophication

20.  Water-saving technology for the home includes:
 Low-flow shower heads (sometimes called energy-efficient shower heads as they also use less
energy, due to less water being heated).[
 Low flush toilets and Composting toilets. These have a dramatic impact in the developed world, as
conventional Western toilets use large volumes of water.
 Dual flushed toilets created by Caroma includes two buttons or handles to flush different levels of
water. Dual flush toilets use up to 67% less water than conventiona l toilets.
 Saline water (sea water) or rain water can be used for flushing toilets.
 Faucet aerators, which break water flow into fine droplets to maintain "wetting effectiveness"
while using less water. An additional benefit is that they reduce splashing while washing hands
and dishes.
 Wastewater use or recycling systems, allowing

24. We are so glad that you have been able to learn a little bit
about how we can be a helping hand in the conservation of
water in our world. Taking care of our planet is a big
responsibility. We have only scratched the surface of
conservation of water, but if we all work together, we can
bring about change, not only with water, but with
air, land, energy, waste, and others. Even though you have
completed this task, do not stop here. We encourage you to
try and find out the ways you can help your community to
become active in conservation. Get involved and dig deeper
for life!
