Document Summary
Variations of t w/ depth define the geothermal gradient or geotherm: early evo of earth, origin of planet, earth and other planets formed at essentially the same time. Earths interior: a primitive atmosphere evolved from gases in earths interior, layers defined by physical properties, lithosphere, asthenosphere, mesosphere, inner and outer core, earths surface, continents, oceans, continents, mountain belts. Gneiss and marble: rock cycle (earths subsystem, the loop that involves the process by which one rock changes to another, illustrates the various processes and oaths as earth materials change both on the surface and inside the. Interactions among the individual plates: types, divergent (constructive, convergent (destructive, transform (conservative) 8/31/11: rates and history of plate motion, magnetic anomalies, magnetic field, originates in liquid outer core, lines of force exit and enter earth at magnetic poles(offset from the geographic poles, normal polarity. Joining silicate structures silicon: single tetrahedral are linked together to form various structures including:
