This document is a school report submitted by Suraj Kumar of Class X discussing various topics related to water, electricity, and fossil fuels. It introduces water and its importance for life, describing how humans and animals use water. It then discusses electricity, describing how it is generated from atomic particles and different energy sources used to produce it. The document also covers fossil fuels, explaining where they come from and their importance as the source of 85% of the world's energy, but also their environmental impacts like greenhouse gas emissions, acid rain, and effects on health and land.

3. THE
IMPORTANCES OF
THE WATER

4. 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.

5. 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.

7. THE IMPORTANCES OF THE WATER
FOR THE ANIMALS
In 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.

9. 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.

10. 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.

11. 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.

12. What is Electricity?
Electricity is generated from the motion of tiny
charged atomic particles called electrons and protons!
Protons = +
Electrons = -

13. Types of Sources used to make
Electricity
Thermal
Geothermal
Nuclear
Hydroelectric
Solar
Wind

14. Pictures of each Source

15. 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
Electric Power Grid
Power Plants
Transmission Lines
Substations
Power Lines
Transformers
Electrical Wiring and Circuit Box

17. Fossil Fuels
Produce 85% of the
world’s energyOSSIL
FUELS
85% of the world’s
commercial energy
COAL
NATURAL GAS OIL

18. Fossil Fuels
We get fossil fuels from the dead and decaying plants
and animals that were buried in the land around
millions of years ago.

19. Importance of Fossil fuels
Fossil 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.

Huge water use
Slurry pipelines

22. Effects on air
Greenhouse gases
3/4 sulfur dioxide
1/3 nitrogen oxides
1/2 carbon dioxide
Toxics
Mercury
Uranium

23. Acid rain

24. Acidity of rain
pH of 6.0
Kills insects, crabs
pH < 5.0
Kills fish, trees
