The movement of the plates creates three ... These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts ...

Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

The findings could transform researchers’ understanding of plate tectonics and how plate movement might be shaped by these ancient, fixed anchors near Earth’s core, Deuss said. Further ...

Plate tectonics is a theory that explains how Earth’s lithosphere—its upper mantle and crust—is split into sections called plates, which move. These movements create mountains, volcanoes and ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

Santorini's earthquakes are intensifying as a rare earthquake swarm continues to rattle the Mediterranean's Aegean Sea. The ...

Where the movement of currents and the mantle converge, like this, plates are pushed together. This is called a destructive or convergent plate boundary. When the plates collide, the denser plate ...
