upper mantle make up the lithosphere. The lithosphere is divided into

individual sections called plates. The rest of the mantle makes up the

asthenosphere. Convection in asthenosphere causes the plates to shift and

move about. We can tell where the plates are or have been because

volcanoes and earthquakes have their own boundaries when the are active.

Tectonic plates have three relationships with each other. The have

convergent boundaries when they collide, divergent boundaries when they

move apart, and transform boundaries when they slide past each other. The
