  1. Quick Question 1.19.2011

  2. What did Wegener do for Geology? • Said that dinosaurs were once real. • Hypothesized that continents are fixed, unmoving objects. • Hypothesized that continents are constantly moving, but could not come up with a because sentence. • Hypothesized that the sea floor was spreading.

  3. What pieces of evidence did Wegener use to support his theory? (Choose 2) • A study of glaciers in Alaska. • A study of rocks in Africa with scrape marks. • A study of where fossils are found on different continents. • A study of how fast glaciers are melting due to climate change.

  4. Where in Earth do convection currents take place? • Inner core / outer core • Outer core / crust • Outer core / Asthenosphere • Lithosphere / asthenosphere

  5. What kind of things happen at plate boundaries? • Shaking of the Earth • Spewing hot magma • Building of Islands • All of the above

  6. Which of the following would be a correct graph title? • IV vs DV. • The effect of the DV on the IV. • DV vs DV. • The effect of the IV on the DV.
