Fossiililähteiden
Fossiililähteiden, often translated as fossil fuels, are natural resources formed from the remains of ancient organisms that lived millions of years ago. These resources, primarily coal, oil, and natural gas, are a result of the decomposition of organic matter under immense pressure and heat over geological timescales. The process begins with the accumulation of dead plants and animals, typically in environments like swamps, shallow seas, or ocean floors. Over eons, layers of sediment bury this organic material, and the absence of oxygen prevents complete decay. The increasing pressure and heat from the overlying rock transform the organic compounds into hydrocarbons, the main constituents of fossil fuels.
Coal, a solid fossil fuel, is primarily composed of carbon, formed from the fossilization of terrestrial plant
