Movement of Earth's continents, illustration. At top is the Earth as it was 250 million years ago (mya). All land was concentrated in a supercontinent known as Pangea. Pangea began to break up during the Jurassic Period, around 175 mya. The Tethys Ocean separated the northern supercontinent Laurasia from the southern supercontinent Gondwanaland. In the Cretaceous Period (bottom), around 50 mya, the continents are closer to their present day positions. | |
