Earthquake
part of the upper mantle located below the crust of the Earth
Asthenosphere
What do you call the people who study Earth's nature, behavior, and history?

How does the movement of plates occur?
The plates move slowly along the Earth’s surface due to the convection currents in the mantle as explained by the plate tectonic theory.
