Theories on plate movement
WebbPlate tectonics is the scientific theory that explains how the Earth’s lithosphere (a large, solid outer layer) is divided into tectonic plates. These plates move on the Earth’s surface and constantly interact. This process is what creates earthquakes, volcanoes, and mountain ranges.
