Plate Tectonics
Continental drift-evidence for drifting continents
Seafloor spreading-evidence for it: Sediment distribution, elevation, paleomagnetism
What causes the magnetic field of the earth? How is paleomagnetism useful for determining age
of rocks. Magnetic field reversals. What is magnetic inclination?
What are the main types of crust-What are the main differences between them?
Plate boundary types
For each main type, know the types of associated features, a couple of geographic
examples, and the effects of having different types of crust (oceanic and continental)
interact
Convergent-Subduction zones and trenches,
Type of lithosphere determines types of features
Oceanic-Oceanic
Oceanic-Continental
Continental-Continental
Divergent-Mid-ocean ridges and rift valleys, areas of relatively high elevation due to high heat
flow
Transform -Strike-slip faults
