Tectonic plate boundaries are the edges where two or more of the Earth's tectonic plates meet. These boundaries can be classified into three main types: divergent, convergent, and transform. At divergent boundaries, plates move apart, creating new crust, while at convergent boundaries, plates collide, often leading to mountain formation or subduction. Transform boundaries occur when plates slide past each other, causing earthquakes. The movement of tectonic plates is driven by forces within the Earth, such as mantle convection. These interactions at plate boundaries are responsible for many geological events, including earthquakes, volcanoes, and the creation of mountain ranges. Understanding these boundaries helps scientists predict geological activity and assess natural hazards.
