Fossil fuels are comprised of three main types: coal, oil, and natural gas. Coal formed from plant matter that accumulated in swamps millions of years ago, became buried, and was subjected to heat and pressure over time. Oil is formed similarly from decayed plant and animal matter and is extracted using massive drills. Natural gas is composed of remnants of decayed organisms subjected to pressure underground and is used for heating, cooking, and some vehicles.

2. What is fossil fuels?
There are three types of fossil fuels , they are :
coal; oil; natural gas. We use coal for
barbeques, ( did you know in the olden times
they used coal for ships and trains.)

3. Natural gas
Natural gas is used for heating, cooking and some types of
cars.
Natural gas is a fossil fuel that can be formed in
different ways. The widely held theory of the origin
of natural gas is that it is composed of the remnants
of decayed plant and animal matter that has been
subjected to immense pressure under the earth’s
crust over millions of years. This formation of
natural gas is referred to as thermogenic methane
and it is made in a similar fashion to oil.

4. Oil
oil is used for running engines or machines.
Oil is formed by…….
Thousands and thousands of years ago,
when the plants and animals died, leaves
and sand and dirt and parts of the earth
fell onto the dead plants and animals and
that’s how we got oil.
They use massive drills to get the oil from
under the water.

5. Coal
Coal is used for barbeques, heating and in the olden days they used
coal Coal wasand trains.
for ships formed millions of years ago when the earth was
covered with huge swampy forests where plants - giant ferns,
reeds and mosses - grew. As the plants grew, some died and fell
into the swamp waters. New plants grew up to take their places
and when these died still more grew. In time, there was thick layer
of dead plants rotting in the swamp. The surface of the earth
changed and water and dirt washed in, stopping to decaying
process. More plants grew up, but they too died and fell, forming
separate layers. After millions of years many layers had formed,
one on top of the other. The weight of the top layers and the water
and dirt packed down the lower layers of plant matter. Heat and
pressure produced chemical and physical changes in the plant
layers which forced out oxygen and left rich carbon deposits. In
time, material that had been plants became coal.
