Solarsystem

  1. 1. SOLAR SYSTEM • 9 Planets – or 8????? • 99.86% mass of the SS is the sun • Due to the gravitational pull, the sun is the central object
  2. 2. Gravity’s Influence on Orbits
  3. 3. EARTH’S MOTIONS • Rotation – Earth rotates on it’s axis (23.5 degree tilt) • This causes day and night – 24 hours
  4. 4. Seasons <ul><li>The tilt of the earth causes the seasons </li></ul><ul><li>Because of the tilt to the sun’s position relative to the equator constantly changes. </li></ul>
  5. 5. Tilt of the Earth
  6. 6. Moon, Earth and Sun <ul><li>• Scaled Model </li></ul><ul><li>• Sun 28’ in diameter </li></ul><ul><li>• Earth 8 cm in diameter </li></ul><ul><li>• Moon 2 cm in diameter </li></ul><ul><li>– If the globe is used to represent </li></ul><ul><li>Earth, the Moon would be about </li></ul><ul><li>3” in diameter and would need to </li></ul><ul><li>be 30 feet away from the Earth. </li></ul>
  7. 7. Can we make our solar system to scale? <ul><li>http://www.exploratorium.edu/ronh/solar_system/ </li></ul>
  8. 8. Earth’s Moon <ul><li>The moon rotates and revolves at the same rate = 27.3 days </li></ul><ul><li>• Same side of the moon always faces the Earth </li></ul>
  9. 10. Eclipse <ul><li>• Occurs when the Earth or moon temporarily blocks the sunlight reaching the others. </li></ul>
  10. 11. Solar Eclipse
  11. 12. Solar Eclipse <ul><li>Occurs when the moon moves directly between the sun and the Earth and casts a shadow on part of the Earth </li></ul><ul><li>Only involves .5% of the Earth’s surface </li></ul>
  12. 13. Lunar Eclipse
  13. 14. Lunar Eclipse <ul><li>Occurs when the Earth passes between the sun and the moon and blocks sunlight from reaching the moon </li></ul>
  14. 16. Ocean Waves <ul><li>• 2 types </li></ul><ul><li>Wind – height will depend on speed, distance and length of the wind blowing </li></ul><ul><li>Tides – gravitational force of the moon, sun and Earth </li></ul><ul><ul><li>Tides are long waves that result in the periodic change in the surface level of the ocean. </li></ul></ul><ul><ul><li>Some areas experience 2 high tides and 2 low tides </li></ul></ul>
  15. 18. Tides <ul><li>Tidal Range is the difference between high and low tides. </li></ul><ul><li>The moon’s gravity exerts a strong pull on the Earth and causes high tides. </li></ul><ul><li>The rotation of the Earth causes the movement of the tides. </li></ul>
  16. 19. Earth–Moon–Sun Positions and the Tides
  17. 20. Tides <ul><li>Spring Tides – Moon, Earth and Sun are lined up </li></ul><ul><ul><li>High Tides Higher </li></ul></ul><ul><ul><li>Low Tides Lower </li></ul></ul><ul><li>Neap Tides – Moon, Earth and Sun form right angles </li></ul><ul><ul><li>High Tides Lower </li></ul></ul><ul><ul><li>Low Tides Higher </li></ul></ul>
