Understanding Plate Tectonics and Its Significance
What Is Plate Tectonics?
Plate tectonics is the scientific theory explaining the movement of Earth's lithosphere, which is divided into large, rigid plates that float atop the semi-fluid asthenosphere. These tectonic plates are constantly shifting, interacting at their boundaries, leading to a variety of geological phenomena.
Why Is Plate Tectonics Important?
Understanding plate tectonics is crucial because:
- It explains the formation of mountains, ocean trenches, and volcanic arcs.
- It helps predict seismic activity and earthquake risks.
- It provides insights into the Earth's geological history and future transformations.
- It is fundamental for natural resource exploration, such as oil, minerals, and groundwater.
