2. Millions of years ago, a large number of plants and ferns
grew on Earth.
These plants and ferns died in swamps, around riverbanks
and got covered with soil and mud and slowly sank into
the ground.

As the years passed, the Earth's heat and the weight of
the ground changed these dead plants into coal.
To extract coal, it needs to be dug out. Coal is usually
found in layers, or seams underground.

3. ADDITIONAL INFORMATION
As fossil fuels like natural gas and oil, coal is formed by the
transformation of organic matter. Plants that lived in vast
swamps 300 million years ago are the source of most of
the coal that is mined today. As those plants died, they
sank into the swamps and were covered with sediments.
Gradually, they decomposed into peat. As the peat sank,
ground heat and pressure removed hydrogen, oxygen and
nitrogen from it to leave mostly carbon. This is what we
know as coal.

4. Coal is classified by its carbon content- the greater the
carbon content, the more heat it gives off when burnt. The
lowest grade of coal is lignite, followed by sub-bituminous
coal, bituminous coal and anthracite, which is 98 percent
carbon.
PROJECT
Use coal to draw. Break the piece of coal that you can
use like a pen for drawing.
Try burning different types of coal and see which one
burns the quickest and slowest.
