As our warm up today, we looked at some information and determined if it is evidence or opinion. Then the students had to decide if it is evidence that supports continental drift or not. Next we reviewed the evidence we looked at in class the other day: animal fossils, plant fossils, climate change, rock samples, etc. Even after all the Wegener's evidence, people still didn't believe in Continental Drift. Since Wegener could not explain how the continents moved, he died with out getting any credit. Once they started mapping the bottom of the ocean floor, scientists located the mid ocean ridge which helped to explain the movement of the continents. Here are the notes that go on page 41 in your notebook... Evidence from the Sea Floor. Next, we did a little lab on Convection Currents. Convection currents happen in the mantle, and this circular movement helps push the continents. Lastly, title page 43, "Plate Boundaries". Click on the file below to open up the webquest. Answer questions 1-9 on page 43 in your notebook. Answer the questions using complete sentences. The links are embedded in the handout.
