Plate movement refers to the shifting of the Earth's lithosphere, which is divided into large sections called tectonic plates. These plates float on the semi-fluid layer of the asthenosphere beneath them. Their movement is driven by forces such as mantle convection, gravity, and the Earth's rotation. As the plates move, they interact at their boundaries, leading to various geological phenomena. For example, when plates collide, they can create mountains or cause earthquakes. Conversely, when they pull apart, new crust can form, as seen at mid-ocean ridges. Understanding plate movement is crucial for studying the Earth's geology and predicting natural disasters.
