Supercontinent Cycle

The Supercontinent Cycle is a geological process where Earth's landmasses gradually drift apart and then come back together over hundreds of millions of years. This movement is driven by plate tectonics—huge sections of Earth's crust that float on the semi-fluid mantle beneath. Periodically, these plates merge to form a supercontinent, like Pangaea, and later break apart again. This cycle influences Earth's climate, ocean currents, and biological evolution, shaping the planet's surface and environment over geological time scales.
