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 ...

New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

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 ...

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?

Scientists may have discovered the world's oldest arc-slicing fault in Northwestern Australia's remote deserts. The finding ...

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 ...

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 ...
