There are seven continents and five oceans on our planet, and they are the result of more than 3 billion years of planetary evolution and the crossing of tectonic plates.
The tectonic plates of the Earth’s crust move at about the speed at which nails grow, but when you take a period of a billion years, you see that they have traveled all over the planet.
Mapping the exact movements of these plates over such a long period of time is very challenging. However, for the first time, a group of geologists offered an easily digestible view of a billion years of tectonic plate movement.
Scientists at the University of Sydney have spent four years reconstructing how the masses of land and oceans have changed over the last billion years. As part of a recent study, they animated those changes in a short video.
