Detailed explanation-1: -Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Detailed explanation-2: -Coal forms from dead plants that sink to the bottoms of swamps. The organic matter is buried under sediments and slowly transformed into peat. If the peat is buried under more sediment, it can become coal. There are several kinds of coal.
Detailed explanation-3: -What happens to the remains of dead marine organisms to transform them into oil and gas? Sediments fall on them then they decompose. Why must nations cooperate to reduce ocean pollution?
Detailed explanation-4: -As sediments continued to accumulate, the dead organisms were further buried. High temperature and pressure over millions of years ultimately produced oil and natural gas from these dead organisms.
