Pangaea: Earth’s Supercontinent. Over 300 million years ago, nearly all land on Earth was joined together as one giant supercontinent — Pangaea. It existed for about 160 million years before breaking apart around 175 million years ago, giving rise to the continents we know today. Its formation and breakup reshaped Earth’s climate, ocean currents, and evolution forever. #Pangaea #PlateTectonics #Geology #EarthHistory #ContinentalDrift #Paleogeography #PrehistoricEarth #Supercontinent #ScienceFact
