In the next century, you can expect the Earth’s surface to change dramatically, influenced by plate tectonic movements and the potential formation of future supercontinents.

Plate Tectonic Movements

Plate tectonics, the slow but constant movement of Earth’s large lithospheric plates over the viscous asthenosphere, are powered by mantle convection. This ongoing process means that the continents you see today are not stationary; rather, they’re continually shifting, albeit at a rate of a few centimeters per year—about the speed at which your fingernails grow. Due to these movements, areas that are currently part of North America could eventually drift into different climates and latitudes, altering their environment significantly. Subduction zones, where one plate dives beneath another, can result in powerful earthquakes and volcanic eruptions, reshaping the landscape over time.

Future Supercontinents

The concept of a supercontinent cycle suggests that Earth’s landmasses periodically come together to form a single massive continent, only to break apart again millions of years later. The last supercontinent, Pangaea, began to rift around 175 million years ago. Before Pangaea, there were others like Columbia and Rodinia. As you look forward to the next 100 years, scientists theorize the formation of Amasia, a future supercontinent that could emerge from the existing continents gradually coming together again. While the full formation is far beyond a 100-year timescale, initial stages may become evident in the shifting positions of continents like Eurasia. Regardless of the name or exact configuration, the evolution into a new supercontinent is a significant geological change that’ll be interesting to track.
