Unformatted text preview: Tectonic Hazards – Plate Tectonics REVIEW (Chap. 2) – Scientific Method – Continental Drift Plate Tectonics – Structure of the Earth and Tectonic plate THE NEW STUFF (Chap. 2 and intro Chap. 3) – Modern Evidence for Plate Tectonics – Plate Boundaries – Transform, Convergent, Divergent – Hot Spot Volcanoes – Earthquakes Review Question #1 Which of the following sets of evidence initiated the ideas behind Alfred Wegener’s purposed theory of Continental Drift? (a) Puzzle-fit shape of continents across the Atlantic Ocean (b) Rocks, fossils, and mountain ranges matched up across the Atlantic Ocean (c) Many tropical fossils (leaves, coral reefs, etc…) discovered . in arctic regions (Antarctica) (d) Glaciers/glaciation (ice) in the tropics (e) All of the above Review Question #2 Which answer BEST outlines the difference between Continental Drift and Plate Tectonics? (a) Continental Drift is the most current and widely accepted theory and was born out of the original theory of Plate Tectonics (b) Continental Drift originated in 1912…Plate Tectonics became popular in the mid 1960s (c) Continental Drift = Earth’s “spin” causes continents to “drift” through the oceans; Plate Tectonics = Both oceanic and continental crust is moving due to radiation related to pressure and temp in the earth’s interior (d) Continental Drift = Earth’s “spin” causes continents to “drift” through the oceans; Plate Tectonics = Both oceanic and continental crust is moving due to convection related to changes in heat and density in the earth’s interior (e) Seriously….I have no clue!?!?!
