Instead, the move happened in fits and starts, with continents creeping apart at that single-millimeter-per-year rate for 40 million years, and then suddenly speeding up to 20 times that speed ...

Perhaps initiated by heat building up underneath the vast continent, Pangaea began to rift, or split apart, around 200 million years ago. Oceans filled the areas between these new sub-continents.

Around 200 million years ago, Earth's last supercontinent Pangea began to break apart, with plate tectonics slowly moving the continents into the world we recognize today. Plate tectonics was only ...

The astonishing diversity of mammalian species today stems in part from the continuing breakup of the continents that began some 200 million years ago and sent different landmasses moving apart.

Continents are difficult to define because the Earth is often changing. Originally, about 300-200 million years ago, Earth contained one landmass known as Pangea, a supercontinent that eventually ...
