Fossil fuels

  1. 1. Fossil Fuels By: Annam Bawani
  2. 2. Info About Fossil Fuels <ul><li>Fossil fuels are fuels formed by natural resources such as buried dead organisms that makes natural resources, such as coal, oil and natural gas, containing hydrocarbons. The types of fossil fuels are petroleum, coal, and natural gas.  </li></ul>
  3. 3. Fossil Fuels- Coal <ul><li>Coal was formed thousands of years ago when plants and animals died. As the plants died, they got covered by sand and mud. Underneath the sand and mud, the plants created a sponge like material called peat. The peat was buried by soil and silt and when it put a lot of pressure on it and made it get tighter, it eventually turned into coal. Coal is used as electricity, heat, it can be made into gas and liquids. </li></ul>
  4. 4. Stages of Coal Formation <ul><li>Coal starts out as peat which is a soggy, sponge like material that was compressed under soil and silt for many years. Lignite coal is the lowest ranked coal for it's heat energy and carbon content. Bituminous coal has higher carbon content and contains less water, so it's harder. Anthracite coal has the highest concentration of carbon, it's the hardest coal. But the good side is that it's the cleanest burning coal. </li></ul>
  5. 5. Fossil Fuels- Petroleum/Oil <ul><li>Oil was formed from the remains of animals and plantsthat lived millions of years ago in a marine like place. Over millions of years, the remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call oil. Petroleum is used for making fuel, oil, and gasoline. </li></ul>
  6. 6. Fossil Fuels- Natural Gas <ul><li>The main ingredient in natural gas is methane, a gas (or compound) composed of one carbon atom and four hydrogen atoms. Millions of years ago, the remains of plants and animals decayed and built up in thick layers.  Over time, the sand and silt changed to rock, covered the organic material, and trapped it beneath the rock.  Pressure and heat changed some of this organic material into natural gas — tiny bubbles of odorless gas. Natural gas is used for cooking, washing, drying, heating and air conditioning. </li></ul>
  7. 7. Info About Refineries <ul><li>Refineries are used to separate the various components present in crude oil and convert them into usable products or feedstock for other processes. It's important because it separates all the bad stuff and junk in the fossil fuels so that when we use them, it's clean and not dirty. </li></ul>
  8. 8. Exxon Valdez <ul><li>The Exxon Valdez (oil tanker) going to Long Beach, California hit Prince William Sound's Bligh Reef and spilled 10.8 Galls of crude oil. The clean up was one trial explosion conducted during the early stages of the spill to burn the oil, in a region of the spill isolated from the rest by another explosion. It killed and deformed much of the wildlife and sealife by Alaska. </li></ul>
  9. 9. Deep Water Horizon Oil Spill <ul><li>The oil spill is stemming from a sea floor oil gusher in the Gulf of Mexico. It started with an oil well blowout on April 20, 2010 which cause a huge explosion on the Deepwater Horizon. At first, BP employed ROVs, 700 workers, 4 airplanes, and 32 vessels to contain the oil. Since that didn't work 2 United States Department of Defense sent 2 aircrafts to spray oil disperant. </li></ul>
