Tectonic Plates Theory

The Tectonic Plates Theory explains that Earth's outer layer, called the lithosphere, is divided into large, rigid pieces known as tectonic plates. These plates glide slowly atop the semi-fluid mantle beneath them. Their movements cause processes like earthquakes, volcanic eruptions, and mountain formation. Plates can move apart (diverge), collide (converge), or slide past each other (transform). This dynamic system shapes Earth's surface over geological time, leading to the formation and reshaping of continents, ocean basins, and various landforms. This theory is fundamental to understanding Earth's ever-changing landscape and geological activity.
