2. What are fossil fuels?
Fuels formed by natural resources such as anaerobic
decomposition of buried dead organisms. The age of
the organisms and their resulting fossil fuels is
typically millions of years, but exceeds 2 billion
years.
Fossil fuels range from volatile materials with low
carbon: hydrogen ratios like methane, to liquid
petroleum to nonvolatile materials composed of almost
pure carbon, like anthracite coal. Methane can be found
in hydrocarbon fields, alone, associated with oil, or in
the form of methane clathrates. It is generally accepted
that they formed from the fossilized remains of dead
plants and animals.

3. What are the different types of fossil fuels?
1: Coal-combustible black or brownish-black sedimentary rock
composed mostly of carbon and hydrocarbons.The energy in coal comes
from the energy stored by plants that lived hundreds of millions of years ago.
For millions of years, a layer of dead plants at the bottom of the swamps was
covered by layers of water and dirt, trapping the energy of the dead plants.
The heat and pressure from the top layers helped the plant remains turn into
what we today call coal.
2: Petroleum-Petroleum or crude oil is a naturally occurring,
flammable liquid consisting of a complex mixture of hydrocarbons of various
molecular weights, and other organic compounds, that are found in geologic
formations beneath the earth's surface.
3: Natural gas-natural gas -consisting primarily of methane.
It is found associated with other fossil fuels, in coal beds, as methane
clathrates, and is created by methanogenic organisms in marshes,
bogs, and landfills. It is an important fuel source, a major feedstock
fertilizers, and a potent greenhouse gas.

4. HOW COAL IS FORMED
Consist with hard, black
colored rock-like substance
It is also made up of carbon,
hydrogen, oxygen, nitrogen,
and amounts of sulfur.
3 types of coal: anthracite,
bituminous and lignite

5.  Almost all oil and gas comes from tiny decayed plants, algae, and
bacteria. Oil was formed from the remains of animals and plants
(diatoms) that lived millions of years ago in a marine (water)
environment before the dinosaurs. Over millions of years, the remains
of these animals and plants were covered by layers of sand and silt.
Heat and pressure from these layers helped the remains turn into what
we today call crude oil.The word "petroleum" means "rock oil" or "oil
from the earth."

6.  Natural gas is lighter than air. Natural gas is made out
of methane, which is a simple chemical compound
made up of carbon and hydrogen atoms.This gas is
highly flammable. Natural gas is found near oil in the
ground. It's pumped, just like oil, from wells that tap
into the source and send it to large pipelines.
