is a violent shaking of Earth’s surface. Where are earthquakes common?
Volcanoes, earthquakes, mountains, and other features of Earth’s
surface owe their origin to the movements of
slowly-moving sections of Earth’s crust. At plate boundaries,
plates collide, move apart, move under or over each other, or slide
past one another. The theory of
the plates move, interact, and change the physical landscape.
Gizmo shows a cross-section, or side view, of Earth. (Not to scale.) Above
the cross section is a bird’s-eye view of the same location.
