The document discusses different types of fossil fuels like coal, natural gas, and petroleum that are found in oceans and seas. It explains that before extraction, fossil fuels are combined as crude oil and the process of fractional distillation is used to separate the components by heating the mixture. Fractional distillation is then defined as the separation of a mixture into parts or fractions through heating. The document also mentions some uses of fossil fuels like electricity production, steel production, cement manufacturing, as fuel in steam engines, and producing synthetic fuels.

3.  COAL
 NATURAL GAS PETROLUM
 NUCLEAR POWER

4. WORLD FOSSIL FUEL CONSUMPTION

5.  THESE FOSSIL FUEL ARE FOUND IN OCEANS
SEAS ETC.
 BEFORE THEY ARE EXTRACTED , FOSSIL FUEL
ARE TOGETHER WHICH IS KNOWN AS CRUDE
OIL.
 TO SEPARATE THEM THERE IS A METHORD
CALLED FRACTIONAL DISTILLATION.

6. FRACTIONAL DISTILLATION
IS THE SEPRATION OF A
MIXTURE INTO COMPONENTS
PARTS OR FRACTION SUCH
AS IN SEPRATING BY
HEATING THEM THIS IS
AS FRACTIONAL
DISTILLATION

7.  It is used in production of electricity
,steel production and cement
manufacturing
 It was used as fuel in steam engine
 Producing synthesis fuel
