  1. Plate tectonics Yes, the continents do move! (SC.7.E.6.5)

  2. Pre-assessment 1. Earth’s mantle plays an important role in plate tectonics. Why is the mantle so important to this process? • Earthquakes occur constantly in the mantle, which causes the plates to move. • The mantle is made up entirely of liquid rock, on which Earth’s crustal plates can float. • Heavy metals in the mantle set up strong magnetic fields that attract and repel Earth’s plates. • Temperature differences in the mantle set up convection currents that help to drive the movement of the plates.

  3. Pre-assessment 2. Two tectonic plates collide and one sinks beneath the other. What do you predict will form? • volcanoes • hurricanes • abyssal plains • mid-ocean ridges

  4. Brain Pop Movie: Plate tectonics Alternative interactive BBC video 1. Layers of the Earth • Crust • Mantle (convection) • Outer core (liquid) • Inner core (solid) 2. Types of plate movement • Divergent (sea floor spreading) • Convergent (mountains) • Transform (sliding)
