Explanation:
Petroleum is formed from the remains of dead plants and animals.
When plants and animals die, they sink and settle on the seabed.
Millions of years ago, these dead wildlife and vegetation decomposed and got mixed with sand and silt.
Certain bacteria helped in the decomposition of this organic matter and caused some chemical changes.
Matter consisting of largely carbon and hydrogen was left behind. However, as there is no sufficient oxygen at the bottom of the sea, the matter could not decompose completely.
The partially decomposed matter remained on the seabed and eventually was covered with multiple layers of sand and silt.
This burying took millions of years, and finally, due to high temperature and pressure, the organic matter decomposed completely and formed oil.
