Crude oil [crude oil: Crude oil is formed from the remains of small animals and plants that died and fell to the bottom of the sea.Their remains were covered by mud. As the sediment was buried by more sediment, it started to change into rock as the temperature and pressure increased.he plant animal remains were cooked by this process and changed into crude oil.] - sometimes called petroleum-is found in the Earth's crust. Millions of years ago small animals and plants died and fell to the bottom of the sea. Their remains were covered by mud. 1  Page. 2  1. 3  2. 4  3.
It was formed when the remains of animals and plants from millions of years ago were covered by layers of sand. Heat and pressure from these layers turned the remains into crude oil. This process is why crude oil is called a fossil fuel. Crude oil is extracted and used to make fuel and other petroleum products.Hydraulic fracturing is one method used to extract oil and natural gas from deep shale formations. Crude oil is a mixture of a wide variety of constituents.It consists primarily of hydrocarbons, which are chemicals composed of hydrogen and carbon. Crude oil also contains hundreds of substances that include benzene, chromium, iron, mercury, nickel, nitrogen, oxygen, sulfur, toluene, and xylene.t was formed when the remains of animals and plants from millions of years ago were covered by layers of sand.
