Where convection currents push plates together, destructive plate boundaries (margins) are formed. Constructive plate margins close constructive plate marginAn area where two tectonic plates are ...

These continents are still on the move today. Exactly what drives plate tectonics is not known. One theory is that convection within the Earth's mantle pushes the plates, in much the same way that ...

Since the late 1960s, when plate tectonics and slow, creeping convection of the rocky mantle became accepted, geoscientists have been debating whether convection extends from the surface to the ...

Plate tectonics (from the Late Latin tectonicus ... Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the ...

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?

Understanding plate tectonics is key to grasping how the Earth’s geology works and how oceans and continents came to be.
