Understanding Oil: Formation, Extraction, and Impact

Oil, also known as petroleum or crude, is a thick black liquid primarily composed of hydrogen and carbon. It contains trace elements like sulfur, nitrogen, and oxygen. Oil deposits formed millions of years ago from dead marine organisms buried under sedimentary rock, subjected to heat and pressure, transforming into oil. This process makes oil a fossil fuel. Oil is found in underground reservoirs and extracted through drilling. Once extracted, it is transported to refineries to produce products like gasoline and plastics. Oil powers transportation and creates synthetic products but poses environmental and geopolitical challenges.
