Petroleum and its formation










     • Like coal , petroleum is also a fossil fuel


          that takes millions of years to form under



          the earth crust.



     • Petroleum  is also known as the “BLACK


          GOLD” or the “crude oil”.




     • Petroleum is formed from the remains of


          dead plants and animals.




     • When plants and animals die, they sink and


          settle on the seabed.
