Fossils fuels

What is fuel?????A material that is burned to give

energy.We use energy to heat homes ,run cars and

airplanes which comes from fuel.

What are fossils fuels?- a fuel that forms from the remains of

decayed plants and animals-it can be used to produce electricity.

-Coal , natural gas and oil are fossils fuels.

Coalcoal is formed when plants of the swamps die and buried for many years.

Oil-oil is found in rocks deep below the

earth surface-people use pumps to bring oil to the

surface .

Oil formation

What is the different between coal and oil?

-coal is formed from decayed parts of plants but oil is formed from decayed parts of animals

So,,,,,, fossils fuels can finish after time its not easily replaced or

reused and this is mean that its nonrenewable source of energy.

Resources of energy

Renewable resources of energy- a resource of energy that can be replaced or used again and

again.

Example:1- solar energy

it’s the energy from the sun that is used to produce electricity

examples: some cars can move by the solar energy.

2-wind energy-the energy of the wind is used to produce electricity (wind turbines)

3-moving water energy.-the energy of the moving water(water falls) is used to turn the turbines and

produce electricity.

Can we produce energy from lakes?

No, because we need the strong moving water from up to down to

produce energy.

Non renewable sources of energy

A resources of energy that cannot be replaced or reusedsuch as fossils fuels because it takes millions of years to form

and once they are used up , they are gone forever.
