Coal is formed when

• sediments cover dead marine organisms and heat converts them in to complex, energy-rich carbon molecules.
• deposits of methane are subjected to high pressure until they condense into crystals.
• swamplands are buried by sediment, the added weight creates heat and pressure that converts the plants into coal.
• oil is put under pressure and hardens.
