Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth's hard outer layer (where we live) is called the crust. It is made up of large slabs called tectonic plates. The plates fit together like jigsaw puzzle pieces far beneath our feet.

New findings provide a greater understanding of plate subduction, or how tectonic plates slide beneath one another. This recycling of surface materials and volatile elements deep into the Earth's ...
