The natural resource primarily used to produce gasoline is crude oil. Crude oil is a fossil fuel extracted from beneath the Earth's surface, formed from the remains of ancient marine organisms subjected to heat and pressure over millions of years. The extraction and refining process transforms crude oil into various petroleum products, including gasoline, which is a key fuel for vehicles. The refining process involves distillation and chemical treatments that separate and convert crude oil into usable products. As a vital component of the global energy industry, gasoline powers transportation systems worldwide, influencing economies and daily life significantly.
