The Slow Carbon Cycle - NASA Earth Observatory

The sedimentary layer was eventually buried deep underground, and the heat and pressure transformed it into coal. Coal and other fossil fuels are a convenient source of energy, but when they are burned, the stored carbon is released into the atmosphere. This alters the balance of the carbon cycle, and is changing Earth's.

What makes coal and oil? | Human World | EarthSky

Jan 17, 2010 . Oil mostly originated as very simple organisms – such as bacteria, algae and plankton. This organic matter – and often the sandstone or line beds that hold the oil – was deposited in marine or lake basins, and in the ocean. Both oil and coal are non-renewable – once we use up all we have, it's gone.
