Tariqs Random Science (TRS) 12/19/2014: Oil was formed from the remains of animals and plants, that lived in a marine (water) environment. The remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call crude oil. The word petroleum means rock oil or oil from the earth. Now did you know that crude oil can be sweet or sour? Crude oil is called sweet when it contains only a small amount of sulfur and sour if it contains a lot of sulfur. Crude oil is also classified by the weight of its molecules. Light crude oil flows freely like water, while heavy crude oil is thick like tar.
