Transcript

  • 1. The Terrestrial Planets
  • 2. Mercury: Innermost Planet
    • Second smallest
    • Absorbs most of the sunlight and reflects only 6 percent back into space
  • 3. Mercury’s Surface Features
    • Cratered highlands
    • Very dense (contains a large iron core for its size)
    • Has very long scarps (deep slopes) that cut across plains and craters
      • Scarps: result from crustal changes as the planet cooled and shrank
  • 4. Mercury’s Surface Temperature
    • Revolves around the sun quickly but rotates slowly
      • One rotation is 59 Earth-days
        • One night last about a month
          • Temperatures drop to -173°C
        • One day last about a month
          • Temperatures rise to 427°C
    • Mercury has the greatest temperature extremes of any planet
  • 5. Venus: The Veiled Planet
    • Named for the goddess of love and beauty
    • Orbits the Sun once every 255 Earth-days
    • Similar to Earth in size, density, mass, and location in the solar system
    • Considered “Earth’s twin”
  • 6. Venus’ Surface Features
    • Covered in thick clouds that visible light can not penetrate
    • Shaped from basaltic volcanism and tectonic activity
    • 80 percent of Venus has plains of old volcanic flow
    • 8 percent of Venus has highlands
  • 7. Venus’ Surface Temperature
    • Greenhouse effect heated the atmosphere to 475°C
      • Atmosphere is 97 percent carbon dioxide, a green house gas
  • 8. Mars: The Red Planet
    • The Martian atmosphere
      • 1 percent the density of Earth
      • Made up of mostly carbon dioxide and small amounts of water vapor
      • Dust storms cause color changes observed from Earth
        • Hurricane forced winds up to 270 kilometers per hour
      • Very cold
  • 9. Mars’ Surface Features
    • Large volcanoes
      • The Olympus Mons is the size of Ohio and 23 kilometers high (2 and ½ times larger than Mt. Everest)
    • Has canyons much larger than the Grand Canyon
  • 10. Water on Mars
    • Some areas show drainage patterns
    • Some indications show groundwater has recently migrated to the surface
      • Some of the escaping water have frozen due to the temperatures that range from -70°C and -100°C
