Chapters 16 & 6-10
Chapter 6 (the Solar System)
• Terrestrial (small, rocky, few moons, closer in) vs.
Jovian (big, gaseous, lots of moons)
• Asteroid/meteor vs. comets
• Why isn’t Pluto a planet?
• General properties of solar system (disk, same rotation, planets isolated, planet
dichotomy)
• Nebular Theory of solar system formation • How it explains what we see
Chapter 16 (the Sun)
• Radiation vs. Convection energy transport
• Different Layers (photosphere, corona, etc.)
• Equilibrium (pressure out, gravity in)
• Fusion in Core. Density/Temp changes with radius • Corona (much hotter!?) magnetic
field
• Magnetic Fields
• • Wrap around planet
• • Sunspots! (11 year cycle)
• • Prominences, solar flares, CME’s, solar wind
Chapter 7 (Earth)
• Structure (Inner core .... Magnetosphere)
• Atmosphere (convection, ozone, greenhouse effect) • Earthquakes (s/p waves map
interior)
• TectonicPlates. Boundaries volcanoes/ earthquakes
• Radioactive dating (concept, “half-life”)
• Magnetosphere (auroras, Van Allen belts) • Tides (tidal forces from Sun & Moon)
• How is Earth special (for life)?
Chapter 8 (Mercury / Moon)
Moon: Basic properties (density, size, structure), Maria vs. Highlands, near vs. far side,
tidal effects from Earth, history of lava flows, no magnetic field, Giant Impact theory of
formation
Mercury: Basic properties (density, size, structure), craters, scarp (contraction in past),
3:2 resonance around Sun, magnetic field, always near Sun in sky

Density/temp changes with radius corona (much hotter!?) magnetic field: magnetic fields, wrap around planet, sunspots! (11 year cycle, prominences, solar flares, cme"s, solar wind. Chapter 7 (earth: structure (inner core magnetosphere, atmosphere (convection, ozone, greenhouse effect) earthquakes (s/p waves map interior, tectonicplates. Moon: basic properties (density, size, structure), maria vs. highlands, near vs. far side, tidal effects from earth, history of lava flows, no magnetic field, giant impact theory of formation. Mercury: basic properties (density, size, structure), craters, scarp (contraction in past), 3:2 resonance around sun, magnetic field, always near sun in sky. Atmospheres: why atmosphere"s stick around , why moon/mercury don"t have them. Craters: cause of craters, age estimates, sizes relative to meteors. Why we don"t see as many on earth.
