How the petrol made

Sir?? these is petrol sir please don't write long paragraph

It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds.[1] The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling (natural petroleum springs are rare). Drilling is carried out after studies of structural geology (at the reservoir scale), sedimentary basin analysis, and reservoir characterisation (mainly in terms of the porosity and permeability of geologic reservoir structures) have been completed.[2][3] It is refined and separated, most easily by distillation, into numerous consumer products, from gasoline (petrol), diesel and kerosene to asphalt and chemical reagents (ethylene, propylene, butene,[4] acrylic acid,[5][6][7] para-xylene[8]) used to make plastics, pesticides and pharmaceuticals.[9] Petroleum is used in manufacturing a wide variety of materials,[10] and it is estimated that the world consumes about 95 million barrels each day.

• Petroleum is formed from the remains of dead plants and animals.
• When plants and animals die, they sink and settle on the seabed.
• Millions of years ago, these dead wildlife and vegetation decomposed and got mixed with sand and silt.
• Certain bacteria helped in the decomposition of this organic matter and caused some chemical changes.
• Matter consisting of largely carbon and hydrogen was left behind. However, as there is not sufficient oxygen at the bottom of the sea, the matter could not decompose completely.
• The partially decomposed matter remained on the seabed and eventually was covered with multiple layers of sand and silt.
• This burying took millions of years, and finally, due to high temperature and pressure, the organic matter decomposed completely and formed oil.
