THAT AUTUMN, A RESEARCH VESSEL called the Glomar Challenger sailed over the Mid-Atlantic Ridge to drill holes and sample sediment. Fossils within the sediment samples they retrieved gave scientists a ...

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 ...

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 ...

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 ...

While it's the reigning theory now, the road to acceptance was long and bumpy for plate tectonics, which describes how large portions of Earth's crust slide, grind, rise and sink ever so slowly across ...

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 ...

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 ...

It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...

But the theory of plate tectonics has rocked this picture of the planet to its core. Plate tectonics reveals how Earth’s surface is constantly in motion, and how its features — volcanoes, earthquakes, ...
