Transcript

  • 1. Chapter 23.1 The Solar System
  • 2.
    • Our solar system consists of 8 planets
    • All planets travel in a elliptical orbit
  • 3. Terrestrial planets
    • Earth like, small and rocky
      • Mercury
      • Venus
      • Earth
      • Mars
  • 4. Jovian planets
    • Jupiter like, huge gas giants
      • Jupiter
      • Saturn
      • Uranus
      • Neptune
    • Pluto fits into neither
    • category
  • 5.
    • Size is the main difference between terrestrial and Jovian planets
      • Earth’s mass is only 1/17 as great as Neptune’s
    • Density, chemical makeup, and rate of rotation are different
      • Density of terrestrial planets average about 5 times the density of water
    Planet Sizes
  • 6. The Interiors of the Planets
    • Substances that make up the planet are divided into 3 groups
      • Gases
      • Rock
      • Ice: Ex. ammonia, methane, carbon dioxide, and water
        • Terrestrial planets are mostly rocky and have metallic substances
        • Jovian planets have large amounts of gases and ices
  • 7. The Atmosphere of the Planets
    • Jovian planets have thick atmospheres of helium, methane, and ammonia
    • A planet’s ability to retain an atmosphere depends on its mass and temperature
      • Jovian planets have greater surface gravities
  • 8. Formation of the Solar System
    • Nebular Theory – the sun and the planets formed from a rotating disk of dust and gases
      • As the speed of rotation increased, the center began to flatten out causing matter to become more concentrated in the center, which is the sun
  • 9.
    • Bits of matter began to clump together, called accretion.
    • Colliding matter formed small, irregularly shaped bodies called planetesimals.
      • In the inner solar system, close to the sun, temperatures were high
        • Only metal and silicate minerals could form.
      • In the outer solar system, it was cold enough for ices to form.
