In between Earth's rigid tectonic plates above and its convecting mantle below is a hot and soft layer known as the asthenosphere. At mid-ocean ridges, upwelling of the hot asthenosphere to the surface of the seafloor forms ...

Plate tectonics, the idea that the surface of the Earth is made up of plates that move apart and come back together, has been used to explain the locations of volcanoes and earthquakes since the 1960s.

We have only known about the existence of the unusual yeti crabs (Kiwaidae)—a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman—since 2005, but already their future survival ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active subduction zones come into being, ...

Since the plate tectonics revolution of the 1960s, scientists have known that new seafloor is created throughout the major ocean basins at linear chains of volcanoes known as mid-ocean ridges. But where exactly does the erupted ...
