Fossil fuels take Response areato form. Coal formation begins in Response area, while oil and natural gas formation begins in Response area. All fossil fuels require heat and Response areain order to form.
Coal formation begins in swamps and marshes where plant material accumulates over millions of years. Oil and natural gas formation begins in marine environments where microscopic plant and animal remains settle on the ocean floor and are gradually buried under layers of sediment. Heat and pressure from the Earth's crust then transform the organic material into fossil fuels.
