Fossil fuels

  1. 1. FOSSIL FUELS By Nasha Dovlatyan
  2. 2. What Are Fossil Fuels? <ul><li>They are non-renewable sources of energy. They are formed from animals or plants that lived over 300 million years ago! </li></ul><ul><li>Fossil fuels are found under the earth’s core. </li></ul>
  3. 3. Types of Fossil Fuels; <ul><li>They are : Coal, Oil, & natural gases. </li></ul>
  4. 4. How are they formed? <ul><li>Most was formed 300,000,000 years ago. Then the earth was covered by steamy swamps. </li></ul><ul><li>They come form the accumulation of dead-land based plants, mostly trees however. </li></ul>
  5. 5. Stages; <ul><li>Process is called coalification. </li></ul><ul><li>It forms from plan remains which have previously died. </li></ul><ul><li>Sub-bituminous </li></ul><ul><li>Bituminous </li></ul><ul><li>anthracite </li></ul>
  6. 6. Oil formation; <ul><li>They form from remains of animals and plants, between 10-160 million years, that lived in the ocean. </li></ul><ul><li>Because of lack of oxygen, the organisms start to slowly decay into carbon-rich compounds. </li></ul>
  7. 7. Natural gas formation; <ul><li>Natural gases are mixtures of hyrdocarbons and gases that occur beneathe the earth. </li></ul><ul><li>Made from decays of living matter from millions of years </li></ul><ul><li>Heat and pressure </li></ul>
  8. 8. Natural gases=fossil fuels <ul><li>Found in the ground </li></ul><ul><li>non-renewable & burning them causes air pollution </li></ul><ul><li>When burning, air energy is produced </li></ul><ul><li>Used for, heart & cooking </li></ul>
  9. 9. Refineries <ul><li>Industrial process plant is when you take crude oil and you process it and refine it for more useful profucts </li></ul><ul><li>Such as: gas, deisal fuel, heating oil. </li></ul><ul><li>Burn oil to create energy. </li></ul>
  10. 10. The Exxon Valdez oil spill; <ul><li>On March 24 th 1989, in Prince William Sound, Alaska. </li></ul><ul><li>What happened was the Exxon Valdez oil spill hit the Bligh Reef and spilled over 10 million gallons of oil into the ocean. </li></ul>
