THE IMPORTANCES OF

THE WATER

INTRODUCTION

The water is a chemical substance with the formula H2O.

The water is very important for life, because it is vital. The animals or humans drink water because the body needs 75% water to do exercise for example: walk.

Water covers 70% of the Earth. Like two thirds parts of the earth.

THE IMPORTANCES OF THE WATER Human uses the water in: - Agriculture: The most important for the agriculture is for

irrigation. - For drinking: Because the body need 75% of water to do

exercise. - Washing: Washing is also an important component of

several aspects of personal body hygiene. - Fire extinction: One of the important use of the water

is the fire extinction. - Recreation: For example swimming, waterskiing, boating,

surfing and diving. - Industrial applications: Water is used in power

generation.

THE IMPORTANCES OF THE WATER FOR THE ANIMALSIn the animal life the water is essential to life.The animals uses are: - Temperature regulation: The

temperature of the animals should be between a specific range.

- Digestion: Water also serves for the lining to the acid in the stomach.

WATER ON THE EARTH· Water cycle: Water cycle consist in this three process:Evaporation: from oceans and other water bodies into the

air and transpiration from land plants and animals into air. Precipitation: from water vapor condensing from the air

and falling to earth or ocean. Runoff: from the land usually reaching the sea.

DON’T WASTE WATER,PLEASE! If you're lathering turn off the water. Don’t play with water. Shower instead of bathing. Fill the washing machine and dishwasher.

WHAT WOULD HAPPEN IF HAD NOT WATER IN THE WORLD If we haven’t water we can’t life in the Earth, because

we can’t drink or eat. The life of the sea are disappear. And the Antarctica don’t exist. The cold of Antarctica disappear the temperature of the planet would very hotter. The name of this cause is Global Warming.

NOW WE CAN’T STOP

THIS PROCESS

What is Electricity?Electricity is generated from the motion of

tiny charged atomic particles called electrons and protons!

Protons = +Electrons = - electron

How do we get Electricity?Energy from one of the sources is converted

by machines at the power plant to Electricity and then put onto the Electric Power Grid

Fossil FuelsWe get fossil fuels from the dead and

decaying plants and animals that were buried in the land around millions of years ago.

Importance of Fossil fuelsFossil fuels are the most important part of

life.As we get electricity, petrol, natural gas, etc.What our life would be without all the

products we get from fossil fuels.
