Transcript

  • 1. THE WORLDSNATURAL RESOURCES By: Chandler Mathis
  • 2. OilOil is a nonrenewable energy source.Oil is the most used resource next to the Sun.When oil is burnt is gives off a gas that is thendiscarded into the atmosphere.
  • 3. More OilMost oil is found mainly in the middle east,because around 80 million years ago,climate change caused the ocean currentsto stop, and the Tethys sea (AKA theMediterranean) stopped flowing.Then all the marine life died, poisoned byhydrogen sulphide, and sank to the bottom.
  • 4. Even More OilWith the northern movement of the Africanplate, and the shrinking of the Tethys sea, thisclump of decomposing material shifted east.The largest oil and gas reserves are in CentralAsia and Siberia.
  • 5. CoalCoal is a non renewable energy source.Coal is mined out from the ground.Coal is the third most used energy source next tothe sun.When coal runs out, we wont have coal grills, coalpencils for shading art, coal filters for makingclean water, and much much more things thatneed coal.
  • 6. More CoalCoal is burnt to heat water, and the steam produced turns aturbine.The turbine is connected to a generator and the generatorgenerates electricity which goes through wires andtransformers until it gets to your home.
  • 7. UraniumUranium is a mined ore that can be used asnuclear fuel for nuclear power reactors, materialfor armor and armor piercing bullets, and alsonuclear weapons.When uranium is mined, the miners needprotection from natural radiation, that theexposed uranium ore causes.
  • 8. Nuclear PowerPressured water nuclear reactors is 1 type of areactor that creates nuclear power by pressurizingwater and sending it through a pipe to cool thevery hot nuclear infused water and turn it intosteam which turns a turbine generator and createsenergy.Nuclear reactors create only a coke bottle ofpollution each year.The U.S. creates about 806 billion kilowatt hoursof electricity from nuclear energy in 2010.
  • 9. Reactor Diagram
  • 10. More Nuclear PowerWhen a nuclear reactor is over heated or suddenlycooled, it will either crack or melt the core.While the nuclear fusion process is going on the core isabout 1,112˚F. Lava is about 1,200˚F.
  • 11. Wind EnergyThe term wind energy describes the process inwhich the wind is used to generate electricity.Wind turbines convert the kinetic energy in thewind into mechanical power. This power can beused for tasks (like grinding grain or pumpingwater) or a generator can convert this powerinto electricity to power homes, businesses,schools, and the like.
  • 12. More Wind EnergyWind turbines, turn in the moving air and power agenerator that makes electricity. Instead of usingelectricity to make wind, like a fan, wind turbines use windto make electricity. The wind turns the blades, which spina shaft, which connects to a generator and makeselectricity.
  • 13. Hydro Hydropower is electricity generated using the energy ofmoving water. Rain or melted snow, usually originating inhills and mountains, create streams and rivers that run tothe ocean. The energy of that moving water can be verystrong.This energy has been used for years. Farmers since theancient Greeks have used water wheels to grind wheatinto flour. Placed in a river, a water wheel picks up flowingwater in buckets located around the wheel. The kineticenergy of the flowing river turns the wheel and isconverted into energy that runs the mill.
