The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

This video reconstructs Pangaea, the supercontinent that existed around 200 million years ago when all modern continents were ...

For the first time in history, scientists have observed the rupture of a tectonic plate in a subduction zone in real time. The study, published in the scientific journal Science Advances, was ...

Early in Earth’s history, the heat left over from the collision that formed the Moon left its surface an ocean of magma. As it cooled, its crust was frequently shattered by massive impacts that ...

For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor. Using advanced ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

On Earth, the land moves. Over millions of years, continents shift and the entire surface of the planet reshapes itself. The driver of all this is plate tectonics: Earth’s surface is divided into ...
