Supercontinent

A supercontinent is a massive landmass composed of multiple continents merged together into a single, vast area. Throughout Earth's history, these supercontinents have formed and broken apart over hundreds of millions of years due to the movement of tectonic plates. Notable examples include Pangaea, which existed around 200 million years ago, and earlier supercontinents like Rodinia. Their formation influences Earth's climate, ocean circulation, and biological evolution. Understanding supercontinents helps scientists learn about Earth's geological past and the dynamic processes shaping our planet over geological time scales.
