Plate tectonics
Yes, the continents do move!
(SC.7.E.6.5)
Pre-assessment1. Earth’s mantle plays an important role in plate tectonics. Why is the mantle so important to this process? A. Earthquakes occur constantly in the mantle,
which causes the plates to move.B. The mantle is made up entirely of liquid rock, on
which Earth’s crustal plates can float.C. Heavy metals in the mantle set up strong
magnetic fields that attract and repel Earth’s plates.
D. Temperature differences in the mantle set up convection currents that help to drive the movement of the plates.
Pre-assessment
2. Two tectonic plates collide and one sinks beneath the other. What do you predict will form?A. volcanoesB. hurricanesC. abyssal plainsD. mid-ocean ridges
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)
