Supercontinent Cycle and Pangaea
Earth’s continents have not always been in the same places. They move slowly over millions of years, constantly reshaping the planet.
A supercontinent is a massive landmass composed of several continents joined together. The most recent one was Pangaea, which formed around 300 million years ago.
Alfred Wegener proposed the concept of continental drift, the idea that continents move over time. He found evidence in matching fossils across continents, similar rock formations, and how continents fit together like puzzle pieces.
Around 200 million years ago, movements in Earth’s crust caused Pangaea to break apart, eventually forming today’s continents. However, Pangaea was not the first supercontinent. Others, such as Rodinia and Columbia, existed millions of years earlier.
The formation and breakup of supercontinents follow a repeating pattern known as the supercontinent cycle. Scientists estimate that this cycle occurs approximately every 500 million years.
If the continents continue moving as they are now, they may come together again in about 200 million years, forming a new supercontinent on the other side of the world.
