How are fossils & energy related

  2. 2. What do you think these pictures look like? They look like parts of animals that were once alive
  3. 3. Fossils A fossil is the remains of a living organism. (It can be a plant or an animal)  Includes bones, teeth, hair or shells 
  4. 4.  Sometimes, living things leave a mark in a material like: mud; by time the materials can harden into rock & these marks are saved in the rocks, this is called: Imprint & it is a type of fossils.
  5. 5. How are fossils made?  A fish lives deep in the Ocean.
  6. 6.  It died & shortly sinks in the ocean’s floor.
  7. 7.  After few weeks, the soft parts of the fish’s body begin to decay.
  8. 8.  After several months, only the skeleton “bones” of the fish is left.
  9. 9.  The bones are covered with the sand.
  10. 10.  As the time passes, the bones become hard like: rocks & fossils are formed.
  11. 11. Steps of fossils formation When the animal dies it is buried fast.  The soft parts of the animal (ex. skin) decay.  Over a long time the sand and bones become rock.  Fossils are made. 
  12. 12. TO BECOME A FOSSIL Must die in a wet environment  Must be buried quickly so the organism is not eaten, decomposed or weathered.  Must have parts capable of being fossilized…hard parts. 
  13. 13. Fuels  To run a car & heat our homes or a plane we need fuel
  14. 14. What is fuel?  A material that is burned to give energy.
  15. 15. Fossils fuels - Fuels that forms from the remains of plants & animals are called: Fossil fuels Coal Oil Natural gas
  16. 16. Coal - Coal is formed when plants of the swamps die & buried for many years.
  17. 17. Oil -Oil is found in rocks deep below the earth's surface. -People use pumps to bring oil to the surface.
  18. 18. Natural gas
  19. 19. Resources of energy  They are the sources from where we get energy.  Resources of energy can be: 1) Renewable resources. 2) Non-renewable resources.
  20. 20. RENEWABLE RESOURCES They are the resources of energy that can be used again & again “replaced”.  Examples: 1) Solar energy: Is the energy from the sun that is  used to produce electricity. {Some cars moves by solar energy}
  21. 21. 2) Wind energy: The energy of the wind is used to produce electricity using wind turbines.
  22. 22. 3) Moving water energy: Is the energy of “water falls” is used to turn turbines & produce electricity.
  23. 23. NON - RENEWABLE RESOURCES They are the resources of energy that cannot be re-used “used again” if they finish.  Examples: Fossil fuels: Fossil fuels take millions of years to form & once they are used up, they are gone forever 
  24. 24. RENEWABLE / NON - RENEWABLE RESOURCES? Solar energy Renewable resource
  25. 25. Coal Non - Renewable resource : Because it’s a fossil fu
  26. 26. Moving water energy Renewable resource
  27. 27. Wind energy Renewable resource
  28. 28. Fire “which we make it using coal” Non - Renewable resource : Because we use coal to make it & coal is a fossil fuel
  29. 29. Natural gas Non - Renewable resource : Because it’s a fossil fu
  30. 30. Oil Non - Renewable resource : Because it’s a fossil fu
