Transcript of Coal

Definition of Coal
Coal is black and brown and it is formed from dead plants and trees that grew in very, very old swamps.
Produced by a mine
Fossil fuel that takes millions of years to form
Used for electricity, iron and steel, plant fertilizer
Different types of coal
Some heating stoves use anthracite coal
Premier coal used for cement making and heating

How coal is formed?
Is coal non-renewable or renewable?
Coal is non-renewable
Where and how is this resource used in the world?
Used everywhere
Coal tar is a thick, dark colored liquid which is why we have shampoos that get rid off dandruff.
Used as a plant fertilizer by breaking it into carbon monoxide and hydrogen gas.
Iron and steel is made by coke which is made from coal
Used for electricity, iron and steel and plant fertilizer
Some heating stoves use anthracite coal

Air pollution (produces greenhouse gases when burning and carbon dioxide)
very dangerous to work in coal mines
when coal runs out it will be a disaster
Burning coal is not eco-friendly
Acid rain is caused by the burning of coal
Mining coal can cause permanent environment damage.
.Water pollution (Coal Production needs lots of water)
People can't live near coal mines because of pollution and noise

Because coal is so easy to get it, it is cheap
Coal can be altered in many ways
Easy to burn
Reliable energy source
Lots of coal.
Different types of coal
Used for electricity, iron and steel, plant fertilizer
Some heating stoves use anthracite coal
Premier coal used for cement making and heating
Different types of coal

Lignite coal used to generate electricity
Anthracite Coal

Hardest coal
When burnt it produces a blue flame
Shiny black rock
Very clean when burnt
Used for space heating
Some heating stoves use anthracite coal

Bituminous coal
Most common coal
It produces a white flame when burnt
Two types of bituminous coal is thermal coal and Metallurgical coal
Thermal coal
Used to fire power plants so they produce steam .
Steam is used for electricity
Metallurgical Coal
Used in the process of making coke to make steel
Coke is a hard, black rock made out of carbon

More then 81% of coal is used by power plants in the U.S. to generate electricity.
In the United States the most common fuel for generating electricity is coal
Australia's coal consumption is eighth in some year
Used everywhere
Australia is the top 10 coal producers and top 10 steel coal producers in 2011.

By Raj and Henry
Disaster if coal runs out
Used for making coke
reason why we
have iron and steel, plant fertilizer and mining
Millions of years to form
Black and Brown
Different types of coals
Lots of coal
Used everywhere
One of the statistics said that coal is getting used more and more as time passes
Fossil Fuel
Some heating stoves use anthracite coal

Why coal is important?
Used as a fuel for lots of things.
Used for producing iron and steel, coke, plant fertilizer, and electricity
It get's used more and more every year
China uses coal a lot so it would be a disaster if it ran out.
.Countries depends on it.
When it runs out companies who sell materials made by coal will be broke

First formed 300 million years ago
Formed from dead tree's and plants in tropical swamps
Tree's and plants fell underwater in swamps
They could not rot fully because they were underwater.
Remains of plants and trees built up forming peat.
.Rocks came on top of the peat
Pressure from the rocks and the earths crust caused reactions.
Reactions turns peat to coal.

When it runs out we may have to look for another energy source that might not meet our requirements and we might not be able to produce some stuff that coal could produce.
If our new energy source is hard to find the prices will go up
We depend on it so much that we are not prepared to find another energy source if it runs out
If coal ran out in china they would not have as much products to make and prices will go up because they will have to look for another source of energy which will probably be more expensive.
Australia depends on china for stuff and if it runs out we will have to look for something to depend on
