Supercontinents

Supercontinents are vast landmasses formed when Earth's continents merge together over millions of years due to plate tectonics. These massive land areas can include most of the Earth's continents at a given time and eventually break apart as tectonic plates shift again, forming new configurations. Famous examples include Pangaea, which existed around 300 million years ago, and previous supercontinents like Rodinia and Gondwana. Their cycles of formation and breakup influence Earth's climate, sea levels, and biological evolution, shaping the planet's geological and ecological history.
