Solar system webquest

  1. 1. Solar system Webquest: The Planets By: Brian Fu
  2. 2. General Information <ul><li>Revolve-The process of circling of a smaller object around a larger object. </li></ul><ul><li>Rotate-The process of spinning of an object on its axis. </li></ul><ul><li>8 Planets have been found in our solar system. </li></ul><ul><li>Inner planets include: Mercury, Venus, Earth and Mars </li></ul><ul><li>Outer planets include: Jupiter, Saturn, Uranus, Neptune </li></ul><ul><li>Difference-Inner planets are solid, but Outer planets are gas planets with rings. </li></ul><ul><li>Inner planets were constantly bombarded by asteroids and meteorites in the first 600 millions of years of existence. </li></ul><ul><li>Orbit-A specific path followed by a planet, satellite, etc. </li></ul><ul><li>Requirements for Planets-an object must be in orbit around the Sun, have enough mass so that it has become round in shape due to its own gravity, and have cleared out its orbital path around the Sun </li></ul><ul><li>Dwarf planet-  class of objects which met the first 2 requirements, but failed the third. </li></ul><ul><li>Dwarf planets include: Pluto, Ceres, Eris. </li></ul>
  3. 3. Mercury <ul><li>Solar wind and an Iron Bearing Core cause Mercury’s atmosphere. </li></ul><ul><li>Mercury’s Atmosphere contains Helium and Sodium </li></ul><ul><li>Impact Cratering, Volcanism, and Tectonic Activities shaped Mercury </li></ul>
  4. 4. Venus <ul><li>Venus is called the Evening star because it is the brightest planet you can see from Earth </li></ul><ul><li>Venus’s Atmosphere is made of Carbon, Oxygen, Hydrogen, and Sulfur </li></ul><ul><li>Retrograde Rotation- Having a direction which is opposite that of similar bodies. </li></ul><ul><li>Venus rotates slower than it revolves. </li></ul><ul><li>On Venus the Sun would rise from the West because of the Retrograde rotation. </li></ul><ul><li>Venus is the hottest planet because its atmosphere acts as a Green House effect and keeps the heat in. </li></ul>
  5. 5. Earth <ul><li>Oxygen, nitrogen, argon, water vapor, carbon dioxide, neon, methane, krypton, helium, xenon, hydrogen, nitrous oxide, carbon monoxide, nitrogen dioxide, sulfur dioxide, and ozone make up our atmosphere. </li></ul><ul><li>Our atmosphere protects us from meteors and radiation </li></ul><ul><li>The rotational tilt of Earth is 23.5 degrees </li></ul><ul><li>The rapid spin and the liquid hot metallic cores cause a magnetic force. </li></ul><ul><li>The Moon is the Earth’s Satellite. </li></ul>
  6. 6. Mars <ul><li>Some meteorites on Earth are from Mars and there is evidence for bacteria on Mars </li></ul><ul><li>CO2 is the Primary Compound in Mars atmosphere. </li></ul><ul><li>The Iron in the soil makes Mars look red </li></ul><ul><li>Olympus Mons is one of the largest volcanoes in our solar system. </li></ul><ul><li>Phobos and Deimos are the satellites of Mars. </li></ul>
  7. 7. Jupiter <ul><li>The rapid spin of Jupiter cause the North and South Pole to flatten. </li></ul><ul><li>Jupiter’s atmosphere is made of hydrogen, helium, nitrogen, and sulfur. </li></ul><ul><li>The Giant Red Spot is a hurricane-like storm that has been spotted since Jupiter was discovered. </li></ul><ul><li>Jupiter has 63 natural satellites in all. </li></ul><ul><li>Io, one of Jupiter’s satellites, is volcanically active. </li></ul>
  8. 8. Saturn <ul><li>Saturn’s atmosphere is made up of Hydrogen and Helium. </li></ul><ul><li>The rings of Saturn may have been caused by particles of its satellites. </li></ul><ul><li>The rings are composed of water ice and dust </li></ul><ul><li>Saturn has such a low density that it could float in water </li></ul><ul><li>A season on Saturn can last for 7 years. </li></ul>
  9. 9. Uranus <ul><li>Uranus is tilted 98 degrees so it looks like it is rotating on its side. </li></ul><ul><li>Hydrogen, helium and Methane=(CH4) </li></ul><ul><li>Uranus is known to have 27 satellites. </li></ul>
  10. 10. Neptune <ul><li>Ammonia(NH4), helium and methane(CH4) make up Neptune’s atmosphere. </li></ul><ul><li>Neptune has 13 satellites. </li></ul><ul><li>Triton is the biggest satellite of Neptune and astronomers think that it was captured by Neptune’s gravitational pull. </li></ul>
  11. 11. Pluto <ul><li>Charon, Nix, and Hydra are Pluto’s moons </li></ul><ul><li>Through spectroscopes scientist found out that there was methane frost on Pluto. </li></ul><ul><li>Charon is unusual because it is almost half the size of Pluto. </li></ul>
  12. 12. Ceres <ul><li>Ceres takes about 4.6 Earth years to complete one revolution </li></ul><ul><li>Ceres was once considered an asteroid because it was in the Asteroid belt between Mars and Jupiter </li></ul><ul><li>Its surface is covered with water, ice, clay ,and carbonates. </li></ul>
  13. 13. Eris <ul><li>Eris’ original name was Xena </li></ul><ul><li>It takes 557 Earth Years for Eris to complete a revolution around the Sun </li></ul><ul><li>Eris has a moon called Dysnomia </li></ul><ul><li>Eris is not considered a planet because it didn’t clear out its orbit. </li></ul>
