What if no sun

  1. 2. Warm Up – Page 44 <ul><li>Suppose there were no sun, but we could still live on the Earth, what would it be like? </li></ul>
  2. 3. Brainstorm: <ul><li>On page 44, brainstorm a list of energy sources with your partner. </li></ul>
  3. 4. Sort your energy sources Produced by the Sun (direct or indirect) Not produced by the Sun
  4. 5. Where did you put the following energy sources? <ul><li>Coal </li></ul><ul><li>Oil </li></ul><ul><li>Natural Gas </li></ul><ul><li>Solar </li></ul><ul><li>Wind </li></ul><ul><li>Hydroelectric </li></ul><ul><li>Geothermal </li></ul><ul><li>Tidal </li></ul><ul><li>Nuclear </li></ul><ul><li>Biomass </li></ul>
  5. 6. Solar <ul><li>Energy from the sun. </li></ul>
  6. 7. Wind <ul><li>Wind is caused by the unequal heating of the Earth. The Sun unequally heats the Earth, so wind energy relates to the sun. </li></ul>
  7. 8. Hydroelectric/Water <ul><li>Hydroelectric power comes from moving water. Water moves throughout the planet because of the water cycle. The sun powers the water cycle, so water power is an indirect form of solar energy. </li></ul>
  8. 9. Coal, Oil, and Natural Gas (Fossil Fuels) <ul><li>Fossil fuels formed from the remains of plants. Plants grow and make food through photosynthesis, which requires the sun. Without the sun, there would be no fossil fuels. </li></ul>
  9. 10. Biomass <ul><li>Biomass gets energy produces energy from plants. Plants need the sun to survive. Another indirect form of solar energy. </li></ul>
  10. 11. Nuclear and Geothermal <ul><li>Nuclear energy comes from the fission of radioactive material. This material formed at the creation of the solar system. </li></ul><ul><li>Geothermal energy comes from the heat of Earth’s interior/core. This heat is produced by the breaking down of radioactive material. </li></ul>
  11. 12. Tidal <ul><li>Harnessing energy from tide movements. </li></ul><ul><li>Gravity from the moon (70%) and the sun (30%) </li></ul>
