Transcript of "Solar system webquest"

  1. 1. Solar System Webquest: The Planets By: Diana Bok Science 8B Mr. Kowaliuk
  2. 2. General Information: Keywords to know. <ul><li>Revolve : The circular action of a smaller object around a larger object. </li></ul><ul><li>Rotate : The spinning action of an object on its axis. </li></ul><ul><li>Orbit : A specific path followed by a planet, satellite, etc. </li></ul>
  3. 3. General Information: About the solar system <ul><li>There are 8 planets found in the solar system. </li></ul><ul><li>Mercury, Venus, Earth, and Mars are the Inner Planets </li></ul><ul><li>Jupiter, Saturn, Uranus, and Neptune are the Outer Planets. </li></ul><ul><li>Pluto, Ceres, Eris, Haumea, and Makemake are the Dwarf Planets. </li></ul>
  4. 4. General Information: About Inner and Outer Planets <ul><li>Inner Planets: </li></ul><ul><li>solid spheres of rock </li></ul><ul><li>Closest to the Sun </li></ul><ul><li>Have more craters, because of the asteroid and the meteorites </li></ul><ul><li>Outer Planets: </li></ul><ul><li>gaseous spheres with rings </li></ul><ul><li>Far from the Sun </li></ul><ul><li>Bigger in size than the Inner Planets </li></ul>
  5. 5. General Information: More about Planets <ul><li>There are more craters found in the inner planets, because they are closer to the asteroid belt. </li></ul><ul><li>3 requirements to become a “planet”: </li></ul><ul><ul><ul><li>Must be in orbit around the Sun </li></ul></ul></ul><ul><ul><ul><li>Have enough mass so that it has become round in shape due to its own gravity </li></ul></ul></ul><ul><ul><ul><li>Have cleared out its orbital path around the Sun </li></ul></ul></ul>
  6. 6. General Information: Dwarf Planet <ul><li>What? </li></ul><ul><ul><li>a new class of astronomical objects </li></ul></ul><ul><li>When? </li></ul><ul><ul><li>created in 2006 by the International Astronomical Union </li></ul></ul><ul><li>Why? </li></ul><ul><ul><li>Failed the 3 requirements of Planets </li></ul></ul><ul><ul><li>Officially declared that they are not planets </li></ul></ul><ul><li>Pluto, Ceres, and Eris. </li></ul>
  7. 7. The Inner Planets: Mercury <ul><li>Atmosphere: </li></ul><ul><ul><li>The distance from the Sun is very close, so there is no substantial atmosphere. </li></ul></ul><ul><li>2 Elements found in the atmosphere: </li></ul><ul><ul><li>Sodium </li></ul></ul><ul><ul><li>Helium </li></ul></ul><ul><li>3 processes that shaped Mercury: </li></ul><ul><ul><li>impact cratering = crater formation </li></ul></ul><ul><ul><li>Volcanism = lava flooded the surface </li></ul></ul><ul><ul><li>Tectonic activity = the planet's crust moved in order to adjust to the planetary cooling and contracting </li></ul></ul>
  8. 8. The Inner Planets: Venus <ul><li>“ Evening Star”: </li></ul><ul><ul><li>The brightest planet that can be viewed from Earth </li></ul></ul><ul><li>2 Elements: </li></ul><ul><ul><li>Carbon Dioxide </li></ul></ul><ul><ul><li>Sulfuric Acid </li></ul></ul><ul><li>Retrograde Rotation: </li></ul><ul><ul><li>Rotates clockwise slowly, which is different from the other planets </li></ul></ul><ul><ul><li>“ Retrograde”: having a direction which is opposite that of similar bodies. </li></ul></ul>
  9. 9. The Inner Planets: Venus <ul><li>Day on Venus > Year on Venus: </li></ul><ul><ul><li>Rotation of Venus is opposite. </li></ul></ul><ul><li>Sun’s direction in Venus: </li></ul><ul><ul><li>Venus rotates opposite from other planets, so the sun will rise in West and set in East </li></ul></ul><ul><li>Why the hottest: </li></ul><ul><ul><li>First of the solar system, meaning the closest to the Sun. </li></ul></ul><ul><ul><li>Can melt lead during daytime. </li></ul></ul>
  10. 10. The Inner Planets: Earth <ul><li>Atmosphere: </li></ul><ul><ul><li>21% oxygen,78% nitrogen,9% argon. </li></ul></ul><ul><ul><li>other 0.1%=water vapor, carbon dioxide, neon, methane, krypton, helium, xenon, hydrogen, nitrous oxide, carbon monoxide, nitrogen dioxide, sulfur dioxide, and ozone </li></ul></ul><ul><li>Atmosphere protects us from: </li></ul><ul><ul><li>Solar radiation </li></ul></ul><ul><ul><li>Meteors </li></ul></ul>
  11. 11. The Inner Planets: Earth <ul><li>Rotational tilt: </li></ul><ul><ul><li>Axis titled 23.5 degrees </li></ul></ul><ul><li>Magnetic Field: </li></ul><ul><ul><li>Earth has a core of molten iron-nickel. </li></ul></ul><ul><ul><li>The rapid spin of the Earth along with the liquid, hot metallic core causes a magnetic field </li></ul></ul><ul><li>Satellite of the Earth = Moon. </li></ul>
  12. 12. The Inner Planets: Mars <ul><li>Evidence of life: </li></ul><ul><ul><li>Scientists studied meteorites from Mars and found bacteria and other signs that life may have once existed on Mars. </li></ul></ul><ul><li>Atmosphere: </li></ul><ul><ul><li>95% Carbon Dioxide </li></ul></ul><ul><li>Reddish-orange appearance: </li></ul><ul><ul><li>presence of iron in various rocks and soils </li></ul></ul>
  13. 13. The Inner Planets: Mars <ul><li>Olympus Mons: </li></ul><ul><ul><li>The tallest mountain in the solar system </li></ul></ul><ul><ul><li>Over 26km above its base. </li></ul></ul><ul><li>Satellites of Mars: </li></ul><ul><ul><li>Phobos & Deimos </li></ul></ul><ul><ul><li>Asteroids captured by Mar’s weak gravitational field </li></ul></ul>
