- The Earth as we see it today is the result of billions of years of changes on the surface of the planet.
- The movement of tectonic plates determines the arrangement of the continents, and they're constantly in motion.
- A new video combines a wealth of data and condenses it into a 40-second animation showing the drift of Earth's continents over the past billion years.
If you take a glance at a map or globe today, what you're looking at is really just a recent development. The Earth's continents are constantly moving thanks to the shift of the tectonic plates that make up the planet's crust. If you rewind time by millions of years you'd see a much different picture, and if you take the clock back by a billion years, the arrangement of the landmasses on our planet would look totally unrecognizable.
Researchers studying how the tectonic plates move today have been able to look back into the distant past, and by identifying similar types and ages of rocks on different continents, they've discovered what continents used to be connected. Now, along with a new study published in Earth-Science Reviews, researchers have created a brief video cramming a billion years of Earth's evolution into just 40 seconds.
