What is a plate boundary where two plates move toward each other?
transform
convergent
divergent
Most geologists think that the movement of Earth's plates is caused by
conduction
earthquakes
convection currents in the mantle
Earth's magnetic field
The geological theory that states that pieces of Earth's plates are in constant, slow motion, driven by convection currents is the theory of
subduction
plate tectonics
deep ocean trenches
sea floor spreading
Tectonic plates are made of the:
lithosphere
asthenosphere
mesosphere
crust
