Unformatted text preview: Planets are different due to temperature. Outer Planets =gaseous (Jovian) Core= Rock and Ice, next is Liquid Hydrogen H+, next is Liquid Hydrogen H 2, Cloudy Hydrogen Helium Atmosphere Inner Planets =Rocky Inner Core= Fe and Ni (Iron & Nickel) Solid, Outer Core (Fe & Ni) Liquid (magnetic field), Mantle- Fe, Rich Rock(green rock), Crust=Fe-Poor Rock(pink & black) (asthenoshpere [solid playdoh-like] and lithosphere[upper mantle]) *rules apply on all planets (erosion, liquid flow etc) Sun- Core (Nuclear Fusion H+ + H+ ->He), Radioactive Layer (transfer energy by electromagnetic waves), Convective Layer(transfer energy by movement), Photosphere, Corona Electromagnetic energy- space b/w waves is all that matters, travel @ speed of light (Weins Law =wavelength max = [2897umk]/T) Sun-Earth Energy Balance (watts/m 2 ) Incoming=330w/m 2 , 30% incoming gets reflected=Albeda Earth= 15 o C Sun Spots (dark, lower output, dense magnetic field eruption s ) vs. Faculae (dense, bright high output, vary w/ sunspot activity, more of them) Plate Tectonics=outer shell of earth (lithosphere) is broken into 10-20 internally rigid plates in continuous relative motion (1in/yr) (415cm/yr) (Sea Floor=deep trenches, ridges, Mts, Earthquakes, Volcanoes) (Continental Drift=Alfred Wegener [glacial deposits and fossils])...
