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, oil, or natural gas. Fossil fuels formed from the remains of ancient plants and animals.

Detailed explanation-3: -Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor. After millions of years the deposits end up in rock and sediment where oil is trapped in small spaces. It can be extracted by large drilling platforms. Oil is the most widely used fossil fuel.

Detailed explanation-4: -Petroleum-or crude oil-is a fossil fuel that is found in large quantities beneath the Earth’s surface and is often used as a fuel or raw material in the chemical industry. It is a smelly, yellow-to-black liquid and is usually found in underground areas called reservoirs.

Detailed explanation-5: -Over millions of years, heat and pressure from Earth’s crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal. These fuels are called fossil fuels, since they are formed from the remains of dead animals and plants.
