Plate Tectonics Gizmo Answer Key

Gizmo Warm-up Volcanoes, earthquakes, mountains, and other features of Earth’s surface owe their origin to the movements of plates: enormous, 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 plate tectonics describes how the plates move, interact, and change the physical landscape.
