Answer:
It is created when, over millions of years, layers of decomposing plant and animal matter are exposed under the Earth's surface to extreme heat and pressure.
Explanation:
Petroleum is formed by bacteria which is caused by the decomposition of marine organisms for millions of years. That material is under high temperature and pressure due to which a portion of it changes into natural gas and the liquid comes out as crude oil or mineral oil. Mineral oil is a colourless and odourless one which is a by-product of petroleum. These are also known as fossil fuels.
