The theory of plate tectonics explains that the Earth's lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere beneath. Pangaea, the supercontinent that existed around 335 million years ago, formed as these plates converged and collided, bringing landmasses together. Over time, the movement of these tectonic plates caused Pangaea to break apart, leading to the current configuration of continents as they drifted to their present locations. This ongoing process continues to shape the Earth's surface and geological features.
