fossil fuels form when decayed organisms are compressed underground.
Explanation:
Usually, when biotic matter especially algae and plankton die they sink to the bottom of the oceans. They get overlaid by layers of sediments over time. As the layers of sediment increase, the pressure from the overlying weight causes the organic matter (which is largely carbon-based) to be compressed, and high temperatures associated with the high pressure, causing them to metamorphose into crude oil.
