2. What are Fossil Fuels?
They are natural
substances made
deep within the
earth from the re-
mains of ancient
plants and animals.
Over quite some
time the heat
turned these into
fuels and when its
burned it releases
energy.
3. The Three Types of Fossil Fuels
The three main types
of fossil fuels are
coal, oil, and natural
gas.
They all come from
the underground in
similar ways.
The fossil fuels sup-
ply about 90 percent
of the world's energy
4. How is coal formed?
Coal started out as a large
fern and tree like plants that
grew in swamps.
Plants died and then piled
up at the bottom of the wa-
ter.
They were buried under wa-
ter and composed on by
bacteria and the plants de-
cayed into brown stuff called
peat.
The peat was covered with
mud and sand which was
smashed together to heat it
up which squeezed out wa-
ter and carbon.
5. Stages of Coal
The layers of coal are
formed called seams.
Coal then will be
mined out of the
ground.
Coal is estimated to
last another 200
years.
It is also provides 27
percent of the world's
energy.
6. What is coal used for
Coal is used for 40
percent of the world's
electricity.
Electricity is made
from plants when
coal is burned to
change water into
steam and steam
turns into turbine.
Coal produces car-
bon dioxide.
7. How is oil formed
Oil was formed by tiny plants
and animals that were called
plankton
The plankton then died and
sank to the bottom of the
lakes and seas.
They also were buried under
layers of sand and mud.
They were then squeezed
together to turn into a hard
rock.
The bacteria then munched
the plankton which changed
into dark ooze.
8. What is oil used as a fossil fuel
Crayons
Bubble gum
Dish washing liquids
Eye glasses
Tires
9. How is natural gas formed
Natural gas is formed
just like oil
The planktons died
and sank in the lakes
and seas.
The gas would be
drilled out of the
ground too.
It is made up of
methane, butane,
propane, and ethane.
10. How is natural gas used as a fossil
fuel
Electricity
steel
gas
11. What are refineries and why are they
important to production of fossil fuels
Refineries are indus-
trial process plant
where crude oil is
processed into more
useful petroleum
products.
It is important to the
production of fossil
fuels because it helps
make plastic and
gasoline which are
necessities to our life.
12. Exxon Valdez
It was an oil spill in
Prince William
Sound, Alaska
On March 24,1989
It was spilled there
about an estimate of
10.8 million US gal-
lons.
It was the largest oil
spills in US waters
13. Deep Water Horizon oil catastrophe
The spill was on April
20,2010.
It was from the sea
floor of the Gulf of
Mexico.
This caused an ex-
plosion in the south-
east of Louisiana
coast.
