- As they died, they sank to the bottom of swamps and oceans and over millions of years started decomposing under layers of sand, clay, and other minerals.
- Fossil fuels are a group of energy sources that were formed from ancient plants and organisms in the carboniferous period approximately 360-286 million years ago even before the ancient dinosaurs. At that time the land was covered with swamps filled with organisms and plants.
- There are 3 types of major fossil fuels. Coal was formed from ferns, plants, and trees which hardened due to pressure and heat.
- Oil was formed from small organisms like zoo plankton and algae where pressure caused the more complex organic matter to decompose.
- Natural gas was formed by the same processes as oil, only was exposed to more heat and pressure causing it to further decompose and turn into a gaseous form.
- More heat and pressure
- Fossil fuels have a variety of applications and products from electricity production to transport fuels, from plastic to cosmetics to even some medicines. These resources have powered industrialization over history and continue to so today.
