If this was the case, then mountains would be spread evenly over the Earth’s surface. We know that this is not the case. Wegener suggested that mountains formed when the edge of a drifting ...

New research suggests melting ice sheets are warming global temperatures which may speed up continental drift, creating ...

Scientists believe that the motion of Earth's continents through plate tectonics has been largely steady over millions of years. New research, however, suggests this drift can speed up or slow down ...

Learn how a computer simulation demonstrates that tectonic activity may be less slow and steady than previously thought.

Plate tectonics is geology’s Theory of Everything. The realisation in the 1960s that Earth’s crust is made of fragments ...

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 ...

Discoveries of the Mid-Ocean Ridge and the work of Harry Hess and others led to the development of plate tectonics. Though not without problems, this theory has gained wide acceptance. It is the ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

A boundary where the plates slide past one another without moving towards or away from each other. If the plates move a significant distance very suddenly, this causes an earthquake. There are no ...

Around 10,000 years ago as the last Ice Age drew to a close, the drifting of the continent of North America, and spreading in ...
