Through a comprehensive synthesis for the basic principles of plate tectonics and their geological corollaries, a holistic model is proposed for structures, processes and products of plate ...

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 ...

Plate Tectonics The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions.

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics—the movement of large pieces of Earth's outer shell—evolved over the planet's ...

Scientists have uncovered one of the most exciting geological discoveries of the decade – the long-lost Pontus tectonic plate. This ancient “mega plate,” which once spanned an astonishing 15 ...

Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million years earlier than scientists thought. That, in turn, suggests that the movement of large ...

Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics.

Here's What'll Happen When Plate Tectonics Grinds to a Halt A new study says we may only have another 1.45 billion years to enjoy the dynamic action of Earth’s geologic engine.

One of the worst earthquakes in European history ripped through Portugal in 1755, causing a tsunami, fires and shaking that ...

If plate tectonics, oceans and continents are rare on worlds throughout the universe, that is.
