The Earth. Layers of the earth Core/Mantle/Crust-names based on composition Inner core/outer core/mesosphere/asthenosphere/lithosphere-names based on physical properties Heat transfer and models of convection in the mantle, Temp. and Pressure changes Plate Tectonics Continental drift-evidence for drifting continents includes glacial deposits, flora and fauna found on different continents, jigsaw fit of continental margins Championed by Alfred Wegener in the early 1900s 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, Divergent-Mid-ocean ridges and rift valleys Transform -Strike-slip faults Passive Continental Margin continental and plate boundary are not the same. Typically results from a divergent plate boundary-> continental rifting and sea floor spreading Active Continental Margin continental and plate boundary in the same place. Either a transform boundary or a convergent boundary with mountain building and/or volcanoes.
