2. September 13, 2012 Title: Plate Tectonics L.O.: 1.To explain the continental drift theory. 2.To explain the plate tectonics. Keywords 1.Tectonic plates – Large slabs floating on the earth’s mantle. 2.Plate Tectonic – The idea that plates moving in the earth mantle determines the layout of the continents and oceans and causes volcanoes and earthquakes. © Dwight Sutherland

3. TASK: Describe how the earth has changed in the maps below. The layout of the continents and oceans have changed because of continental drift. © Dwight Sutherland

4. What is continental drift? Continental drift is an idea first put forward by Alfred Wegner, a German scientist. Millions of years ago the earth was at one point one super continent called Pangaea. Plate tectonics cause Pangaea to split into 2 large continents; Laurasia and Gondwanaland. Plate tectonics cause the 2 large continents to split into smaller continents like we have today. In other words the continents are drifting apart. This is called continental drift. TASK: Label where each of the continents are on the maps to below. Earth TodayEarth 200 million years ago Earth 225 million year ago © Dwight Sutherland

6. Lesson recap TASK: What is: continental drift? plate tectonics? a plate? tectonic movement? © Dwight Sutherland

7. TASK: Watch the video on plate tectonics. Look for; What cause the continents to drift/move? What are plates made of? Why do the plates to move? © Dwight Sutherland

8. TASK : Use the following keywords to explain the plate tectonic theory.
