Plate Tectonic Theory

Plate Tectonic Theory explains the movement of Earth's outer layer, known as the lithosphere, which is divided into large plates that float on the semi-fluid asthenosphere beneath. These tectonic plates interact at their boundaries, causing earthquakes, volcanic activity, and the formation of mountains. Their movements are driven by forces such as mantle convection, slab pull, and ridge push. This theory helps us understand many geological processes and features on Earth, including continental drift, ocean formation, and the distribution of fossils and minerals across different regions.
