Our planet is constantly changing, howeverimagine what the Earth will look like after 50, 100 and 200 million years is not so simple. The fact is that our rocky planet is a mosaic of tectonic plates that put pressure on each other and create processes that result in oceans and mountains. Despite the fact that we do not notice this, the plates are constantly moving. Thus, according to the generally accepted theory, the gradual movement of plates in the past divided the supercontinent Pangea and continues to this day. Today, taking into account the past of the Earth and armed with modern technologies, we can predict the future movements of the continents. But what changes are happening right now?
Continental Drift and Seismic Tomography
The most popular theory to datestates that in the future a supercontinent like Pangea will reappear on Earth. According to the theory of plate tectonics, the outer shell of the Earth is divided into several plates that slowly glide along the mantle. Over time, this changes the surface of the Earth through the merger or separation of continents. Chris Skotese, professor at the Department of Earth Sciences at Northwestern University, is studying how plate tectonics and climate change will affect the Earth’s future appearance. So, based on the research, Skotese made several animated maps showing how our house will change in 250 million years:
Scientists have proposed various scenarios of howthis process will continue in the future. The unification of continents in areas on the border between the two plates will create large mountain ranges similar to the Himalayas. Other existing ranges will also grow. Greenland and Antarctica will move away from the poles, which will lead to sea level rise worldwide and will completely change the coast as we know it. Most of these events are simple forecasts, and experts agree that making such long-term forecasts is risky.
