Over the past few decades earth scientific have developed the theory of plate tectonics. Why is this theory useful?

The theory of plate tectonics is crucial because it explains the movement of Earth's lithospheric plates and their interactions, which are responsible for various geological phenomena such as earthquakes, volcanic activity, and mountain formation. It provides a comprehensive framework for understanding the distribution of continents and ocean basins over geological time, aiding in the prediction of geological events and the assessment of natural hazards. Additionally, this theory enhances our understanding of Earth's history and the processes that shape its surface.
