Crude oil (also known as petroleum) is a type of fossil fuel found beneath the earth’s surface. It is formed by the gradual build-up of fossilised organic materials such as algae and plankton. As more layers build up, the bottom most layers are heated and subject to pressure, with the combination of heat and pressure leading to the matter transforming into the waxy substance kerogen. Following even more prolonged exposure to heat and pressure, the kerogen eventually becomes transformed into liquid and gases via the catagenesis process. The formation of crude oil occurs from this pyrolysis (heating) process. The range of heat at which kerogen becomes crude oil is called the oil window. Below this range the crude oil remains kerogen and above this point the crude oil becomes a natural gas.QUESTION:Kerogen becomes crude oil after further heating and pressurisation in the catagenesis process.TrueFalseCan not tell

Formation of coal and petroleumCoal and petroleum have been formed from biomass which has been subjected tovarious biological and geological processes. Coal is the remains of trees, ferns, andother plants that lived millions of years ago. These were crushed into the earth,perhaps by earthquakes or volcanic eruptions. They were pressed down by layers ofearth and rock. They slowly decayed into coal. Oil and gas are the remains of millionsof tiny plants and animals that lived in the sea. When they died, their bodies sank tothe sea bed and were covered by silt. Bacteria attacked the dead remains, turningthem into oil and gas under the high pressures they were being subjected to.Meanwhile, the silt was slowly compressed into rock. The oil and gas seeped into theporous parts of the rock, and got trapped like water in a sponge. Can you guess whycoal and petroleum are called fossil fuels?
