Fossil Fuels

All About Fossil Fuels!

Fossil Fuels: a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms

How: Fossil Fuels formed millions of years ago through a long process that slowly transformed the organisms into various types of fuels. This started when living things died, they decomposed and became buried under layers of mud, rock, and sand and other natural materials. Eventually, hundreds and sometimes thousands of feet of earth built up over them. In some areas, the decomposing materials were covered by ancient seas, then the seas dried up and receded.

During the millions of years that passed, the dead plants and animals slowly decomposed into organic materials and formed fossil fuels. Different types of fossil fuels were formed depending on what combination of animal and plant debris was present, how long the material was buried, and what conditions of temperature and pressure existed when they were decomposing.

What's The Difference?

Nonrenewable Energy Source: an energy resource that is not replaced or is replaced only very slowly by natural processes

Renewable Energy Source: energy that comes from resources which are continually replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.

Proven Reserves: are business or political terms regarding fossil fuel energy sources
