New “unprecedented” animations of the Earth show how the planet’s surface has shifted and changed over the past 100 million years.
These animations are the most detailed view of the history of Earth’s topography ever, depicting the rise of mountains, the development of basins, and the transport of large masses of sediments around the globe through erosion.
The animations show the movements of tectonic plates, the large rafts of crust that bump up against each other to form mountain ranges and pull apart to form ocean basins. When these plates dive into the mantle, or Earth’s middle layer, at subduction zones they give rise to planet-shaping volcanoes and earthquakes. But there are other forces shaping the surface, too: Precipitation erodes away the surface, while the rate of weathering alters levels of carbon dioxide in the air, creating a feedback loop that links the land to the atmosphere.
