Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

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, and ...

A new study suggests that plate tectonics -- a scientific theory that divides the earth into large chunks of crust that move slowly over hot viscous mantle rock -- could have been active from the ...

How is plate subduction factory operated during continental collision? How do physical mixing and chemical reaction proceed at colliding continental margins of different depths? How is continental ...

For decades, scientists have accepted a particular theory regarding the evolution Earth’s plate tectonics, but a recent study published in Nature Geoscience could defy this as a team of researchers ...

The division of the Earth's surface into seven major mobile plates is fundamental to our planet's uniqueness, creating a habitable environment and possibly the conditions under which life itself ...

W. Jason Morgan, who in 1967 developed the theory of plate tectonics -- a framework that revolutionized the study of earthquakes, volcanoes and the slow, steady shift of the continents across the ...

For decades, scientists have theorized that the movement of Earth's tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven ...

The summit pyramid of Mount Everest, the highest point on Earth, is built from the remains of creatures that lived on an ancient seafloor roughly 470 million years ago. Limestone near the peak ...

A post–World War II data boom clinched the unifying theory of plate tectonics after decades of debate over whether Earth’s crust was static or mobile, Carolyn Gramling reported in “Shaking up Earth” ...
