Solar system webquest

  1. 1. Solar System Webquest By: Curtis Xuan
  2. 2. Revolution and Rotation <ul><li>Revolve: the action of smaller object circling around a larger object in a path </li></ul><ul><li>Rotate: the action of a small object spinning and turning around by itself </li></ul>
  3. 3. 8 Known Planets <ul><li>Inner planets: Mercury, Venus, Earth, and Mars </li></ul><ul><li>Outer planets: Jupiter, Saturn, Uranus, and Neptune </li></ul><ul><li>The difference between outer planets and inner planets is that the distance from the Sun to outer planets is longer than the distance from sun to inner planets </li></ul><ul><li>There are more craters found on inner planets than the outer planets because outer planets have rings. Also, the Sun has a lot of gravity that keeps the asteroids and meteorites revolving around. </li></ul>
  4. 4. Dwarf Planets (Not Planets) <ul><li>Orbit: a path that is certain and followed by satellites </li></ul><ul><li>Three requirements of being a planet: </li></ul><ul><li>1. Need to orbit around the Sun </li></ul><ul><li>2. Have enough mass to become round </li></ul><ul><li>3. Cleared out its path of orbit around Sun </li></ul><ul><li>Dwarf planets are not considered planets because they don’t meet the requirements of being a planet </li></ul><ul><li>Three Dwarf Planets: </li></ul><ul><li>1. Pluto </li></ul><ul><li>2. Ceres </li></ul><ul><li>3. Eris </li></ul>
  5. 5. Mercury <ul><li>Mercury’s temperature (extremely hot and cold) effected on its atmosphere </li></ul><ul><li>Mercury is consisted of helium and sodium </li></ul><ul><li>Three processes that shaped Mercury: </li></ul><ul><li>1. Large objects struck Mercury </li></ul><ul><li>2. Lava flooded the surface on Mercury </li></ul><ul><li>3. Planet’s crust moved to adjust </li></ul>
  6. 6. Venus <ul><li>Venus is called the “Evening Star” because it’s the brightest planet we see on Earth </li></ul><ul><li>Consisted of Carbon Dioxide and Sulfuric acid, which acts as heater </li></ul><ul><li>Retrograde Rotation means that it’s the opposite of the others (spins clockwise) </li></ul><ul><li>A day on Venus is 243 Earth days and a year on Venus is 225 Earth days </li></ul><ul><li>Sun appear to rise in the west and set in the east because it has retrograde rotation </li></ul><ul><li>Venus is the hottest planet because of the atmosphere, which traps heat </li></ul>
  7. 7. Earth <ul><li>Earth is consisted of nitrogen, oxygen, water vapor, carbon dioxide, methane, etc </li></ul><ul><li>These elements prevent us from harmful solar radiation </li></ul><ul><li>The Earth is tilted at 23. 5° angle </li></ul><ul><li>The Earth’s spinning speed and liquid caused the magnetic field </li></ul><ul><li>Moon is satellite of Earth </li></ul>
  8. 8. Mars <ul><li>Scientists found bacteria on meteorites from Mars, so it’s a sign of life </li></ul><ul><li>The primary element of atmosphere is carbon dioxide </li></ul><ul><li>Mars’s appearance is red because of iron </li></ul><ul><li>Olympus Mons is the highest mountain in the solar system </li></ul><ul><li>Two satellites on Mars are Phobos and Deimos </li></ul>
  9. 9. Jupiter <ul><li>Fast spinning speed caused Jupiter to have a wide equator and flat poles </li></ul><ul><li>Jupiter is consisted of hydrogen, helium, sulfur, and nitrogen </li></ul><ul><li>The Giant Red Spot is a storm that looks like Jupiter we saw when Jupiter was first discovered </li></ul><ul><li>63 satellites have been discovered </li></ul><ul><li>A moon on Jupiter, lo’s surface is higher than any other planets’ surface in Universe </li></ul>
  10. 10. Saturn <ul><li>Atmosphere are made out of Hydrogen and Helium </li></ul><ul><li>Rings are caused by the breakup of old moons </li></ul><ul><li>Rings are composed of water, ice, and dust </li></ul><ul><li>Saturn could even float on water since it’s really light! </li></ul><ul><li>Seasons on Saturn last 30 times longer than seasons on earth. </li></ul>
  11. 11. Uranus <ul><li>Uranus rotates on its side </li></ul><ul><li>Atmosphere are made out of Hydrogen, Helium, and Methane </li></ul><ul><li>Uranus have 27 known satellites </li></ul>
  12. 12. Neptune <ul><li>Atmosphere is consisted of Ammonia, Helium, and Methane </li></ul><ul><li>Neptune has 13 known satellites </li></ul><ul><li>Triton might originally be a dwarf planet, or moon of Uranus or Pluto. It probably got sucked into Neptune's gravitational pull </li></ul>
  13. 13. Dwarf Planets <ul><li>Pluto </li></ul><ul><li>Ceres </li></ul><ul><li>Eris </li></ul>
  14. 14. Pluto <ul><li>The names of Pluto’s moons are Charon, Nix, and Hydra </li></ul><ul><li>Scientists found methane frost on Pluto and water frost on Charon by using spectroscope </li></ul>
  15. 15. Ceres <ul><li>A whole revolution on Ceres is 4.6 Earth Years </li></ul><ul><li>It was once considered asteroids because it was among lots of them </li></ul><ul><li>Surface on Ceres includes water, ice, carbonates, and clays </li></ul>
  16. 16. Eris <ul><li>Eris’s original name is Xena </li></ul><ul><li>A whole revolution is 557 Earth years </li></ul><ul><li>The moon of Eris is called Dysnomia </li></ul><ul><li>Eris is not considered a planet because its orbit isn’t cleared </li></ul>
