The breakup of Pangaea
How did we get to the seven continents that we see on Earth today?
The last supercontinent
200 million years ago Earth’s land was all part of the continent Pangaea and the sea was all one ocean, known as Panthalassa, Greek for ‘all sea’.
Today’s continents emerge
Laurasia and Gondwanaland broke apart into the modern continents 130 million years ago.
Laurasia and Gondwanaland
Pangaea split in two 180 million years ago. Laurasia contained North America, Europe and Asia. Gondwanaland contained Antarctica, Australia and South America.
The Atlantic Ocean widens and the Pacific Ocean shrinks, forcing the continents apart.
