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 ...

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 ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

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 ...

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 ...

W. Jason Morgan, a Princeton University geologist who laid out an influential new vision of our evolving planet, attributing the most powerful upheavals — earthquakes, volcanoes and the formation of ...

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 emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

Readers who went to school before the late 1960s will probably remember that their science teachers couldn't explain why South America and Africa seemed to fit together like pieces in a jigsaw puzzle.

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, ...
