Plate
tectonics
Yes, the continents do
move!
(SC.7.E.6.5)
Pre-assessment
1. Earth’s mantle plays an important role in plate
tectonics. Why is the mantle so important to this
process?
A.
B.
C.
D.
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.
Pre-assessment
2. Two tectonic plates collide and one
sinks beneath the other. What do you
predict will form?
A. volcanoes
B. hurricanes
C. abyssal plains
D. mid-ocean ridges
