Nothing stays the same for long, even the ground we’re on. Earth isn’t just a stable place; it’s always shifting and changing. Beneath our feet lies a dynamic planet made of tectonic plates gliding over a molten layer.
Recently, a group of Australian and Chinese geologists took a fresh look at how these plates have moved over the last 1.8 billion years. They used new data and advanced software to create a 1-minute video showing this incredible history. The video starts today and goes back in time, revealing how our continents have shifted and changed.
At first, we see the continents as they are now. Then, just a few million years back, the plates begin to collide. Around 200 million years ago, we witness the formation of Pangaea, the famous supercontinent during the age of dinosaurs, created nearly 335 million years ago.
As we continue traveling back, we see the rise and fall of other supercontinents, like Rodinia, which formed about 1.35 billion years ago. Interestingly, scientists have long referred to the period between 1.8 billion and 0.8 billion years ago as the “boring billion.” However, recent research challenges this notion, suggesting it was a time of significant geological activity instead of stagnation.
Change isn’t just a matter of the past. Today, Earth is still evolving, just at a slow pace. For instance, Zealandia was confirmed as a continent in 2017, even though most of it is submerged. Another fascinating development is in East Africa, where a massive rift is forming. Over the next 5 to 10 million years, this could split part of East Africa away, creating a new ocean.
As for the Mediterranean region, scientists believe that tectonic activity could transform it dramatically in the distant future. The pressure from colliding tectonic plates may lead to significant changes, possibly erasing the Mediterranean as we know it.
Looking even further ahead, experts predict that in about 200 million years, a new supercontinent could emerge. One theory suggests “Amasia,” where most continents gather around the North Pole. Another possibility is “Aurica,” where land masses could cluster near the equator. These scenarios illustrate a radically different Earth.
In summary, Earth’s surface is a story of continuous change. From ancient supercontinents to future transformations, the journey of our planet is filled with wonder. It reminds us that even things that seem solid can transform over time.
