Crude mineral oil comes out of the earth as a thick brown or black liquid with a b smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea-bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier.
Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.
How does crude oil come out of the earth?
Thick brown or black liquid with mild smell
Thick red brown liquid with strong smell
Mixture of different colours
Mixture of different colours
D.

Sedimentary rocks leads to the formation of oil deposits because
their pressure produces heat and turns deposits of animal carcasses and plants into oil.
it turns heavy and shuts out the oxygen
it becomes hard and forms into rocks to squeeze oil
it becomes hard and forms into rocks to squeeze oil
