Petroleum was formed from organisms living in the sea. As these organisms died, their bodies settled at the bottom of the sea and got covered with layers of sand and clay. Over millions of years, absence of air, high temperature and high pressure transformed the dead organisms into petroleum.

Hey Guyslook, there is an unknown creature .
Hi. are you guys talking about me? I am am a dead organism. I am still here as I did not get decayed yet.
yayyy! finally i have reached the next stage. now as you can see, layers of sand and clay have covered me up.
As you can see, this is the next step(converted to crude oil). As I got converted to crude oil(unrefined petroleum), there are so many constituents inside me(petroloeum). like petrol, petroleum gas, diesel, lubricating oil, paraffin wax etc.The process of seperating the various constituents in me(petroleum) is called refining.
