how do petroleum formed
Answers
Answer:
Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. ... Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels.
Explanation:
How is Petroleum Formed?
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 not 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.
