Discuss in detail the Plate Tectonics theory with diagrams.
The Plate Tectonics Theory
The theory of Plate Tectonics revolutionized our understanding of Earth's surface dynamics by explaining the movement of the lithosphere, its interaction with underlying layers, and the processes shaping the Earth's surface. Proposed in the mid-20th century, this theory integrates and builds upon earlier concepts such as continental drift and sea-floor spreading.
### Core Principles
The lithosphere, Earth's rigid outer shell, is divided into large, interlocking plates that float atop the semi-fluid asthenosphere. These plates move due to convection currents in the mantle, which are driven by heat from the Earth's core. Plate boundaries are zones of significant geological activity, including earthquakes, volcanism, and mountain building.
