Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

Plate tectonics is a scientific theory describing the large-scale motion of seven or eight large plates (depending on how they are defined) and the movements of a larger number of smaller plates of ...

The theory of Plate tectonics – developed from Alfred Wegener’s theory of Continental Drift to explain the movement of the continents – has become the prevailing theory underpinning our understanding ...

Earth's fractured outer shell is in perpetual motion. While usually imperceptible to us surface dwellers, these pieces of a rocky jigsaw puzzle are constantly crashing together, diving beneath one ...
