Fossil fuels Fossil fuels Presentation Transcript

  • Fossil Fuels By: Glizyl Luna
  • What are Fossil Fuels?  They are natural substances made deep within the earth from the re- mains of ancient plants and animals. Over quite some time the heat turned these into fuels and when its burned it releases energy.
  • The Three Types of Fossil Fuels  The three main types of fossil fuels are coal, oil, and natural gas.  They all come from the underground in similar ways.  The fossil fuels sup- ply about 90 percent of the world's energy 
  • How is coal formed?  Coal started out as a large fern and tree like plants that grew in swamps.  Plants died and then piled up at the bottom of the wa- ter.  They were buried under wa- ter and composed on by bacteria and the plants de- cayed into brown stuff called peat.  The peat was covered with mud and sand which was smashed together to heat it up which squeezed out wa- ter and carbon.
  • Stages of Coal  The layers of coal are formed called seams.  Coal then will be mined out of the ground.  Coal is estimated to last another 200 years.  It is also provides 27 percent of the world's energy.
  • What is coal used for  Coal is used for 40 percent of the world's electricity.  Electricity is made from plants when coal is burned to change water into steam and steam turns into turbine.  Coal produces car- bon dioxide.
  • How is oil formed  Oil was formed by tiny plants and animals that were called plankton  The plankton then died and sank to the bottom of the lakes and seas.  They also were buried under layers of sand and mud.  They were then squeezed together to turn into a hard rock.  The bacteria then munched the plankton which changed into dark ooze. 
  • What is oil used as a fossil fuel  Crayons  Bubble gum  Dish washing liquids  Eye glasses  Tires
  • How is natural gas formed  Natural gas is formed just like oil  The planktons died and sank in the lakes and seas.  The gas would be drilled out of the ground too.  It is made up of methane, butane, propane, and ethane.
  • How is natural gas used as a fossil fuel  Electricity  steel  gas
  • What are refineries and why are they important to production of fossil fuels  Refineries are indus- trial process plant where crude oil is processed into more useful petroleum products.  It is important to the production of fossil fuels because it helps make plastic and gasoline which are necessities to our life.
  • Exxon Valdez  It was an oil spill in Prince William Sound, Alaska  On March 24,1989  It was spilled there about an estimate of 10.8 million US gal- lons.  It was the largest oil spills in US waters
  • Deep Water Horizon oil catastrophe  The spill was on April 20,2010.  It was from the sea floor of the Gulf of Mexico.  This caused an ex- plosion in the south- east of Louisiana coast. 
