What is the theory of plate tectonics?

The theory of plate tectonics is a scientific explanation for the movement and interaction of Earth's lithospheric plates. It states that the Earth's outer shell is divided into several large and small plates that float on the semi-fluid asthenosphere beneath them. These plates are in constant motion due to the convective currents in the mantle. The theory explains various geological phenomena such as earthquakes, volcanic activity, mountain formation, and the distribution of continents and oceans.
