How is crude oil formed?
Crude oil is not largely made up of Dinosaurs as many people believe. Instead they are made up of infinite trillions of ancient algae that died and sunk to the bottom of the ocean and seas millions of years ago. These algae lived in the shallow seas of the past, where they took in Carbon Dioxide (CO2) and release the oxygen back to the atmosphere. The carbon was used in the plants life for groth, but when they died all that carbon in the algae sunk to the bottom of the sea and over the eons was covered with silt. Over millions of years the dead algae became closer to the earths mantle with the constant adition of new sediment. Eventually it got close enough to the mantle to start cooking, this burned away the impurities and left the carbon on hydrogen (this is whey oil is called a Hydrocarbon fuel). After being bake some of the oil would avoid being swallowed by the earth or being turned into natural gas and seeped up towards the surface. What keeps the oil from surfacing is cap-stones
