STORY OF COAL(MINDMAP)1.COAL WAS MADE ABOUT 300 MILLIONS

OF YEARS AGO.

6.THIS PROCESS IS CALLED

CARBONISATION.

5.UNDER HIGH PRESSURE AND

HIGH TEMP.,DEAD PLANTS GOT

SLOWLY CONVERTED TO

COAL.4.THE TEMP. ALSO ROSE AS THEY

SANK DEEPER AND DEEPER.

3. DUE TO NATURAL PROCESSES,LIKE

FLOODING,THESE FOREST GOT BURIED UNDER THE

SOIL.AS MORE SOIL COVERED THEM,THEY WERE COMPRESSED.

SON,MANY YEARS AGO ORGANISMS DIED IN THE SEAS AND DUMPED IN DEEP SEA FLOOR AND DUE TO HIGH PRESSURE AND TEMPAND NO AIR THEIR BODY FLUIDS GOT CONVERTED TO PETROLEUM.

WHAT IS STORY OF PETROLEUM?DAD.

STORY OF PETROLEUM

c

Extraction of petroleum

ORGANISMS DIED IN THE SEAS

THEY GOT DUMPED IN DEEP SEA FLOOR

DUE TO HIGH PRESSURE AND

TEMPAND NO AIR THEIR BODY FLUIDS GOT CONVERTED TO PETROLEUM

PETRLEUM

DISCOVERED IN 1867

ITS PRODUCTS ARE MADE

BY A PROCESS CALLED

FRACTINAL DISTILARATI

ON

BY PRODUCTS ARE:-

1.KEROSENE 2.PETROL

3.PETROCHEMICALS4.WAX

5.LUBRICATING OILetc

ALSO CALLED

BLACK GOLD

MOSTLY FOUND IN SEA

MADE FROM DEAD

ORGANISMS

NATURAL GAS

THE GAS LEFT DUE

TO

CARBONISATION

OF PETROLEUM IS

KNOWN AS

NATURAL GAS
