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 ...

Plate tectonics might have gotten a fitful start on the early Earth. Today, the process of Earth’s crustal movement called plate tectonics dictates nearly everything about the planet’s appearance, ...

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, ...

Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.

Plate tectonics, the idea that the surface of the Earth is made up of plates that move apart and come back together, has been used to explain the locations of volcanoes and earthquakes since the 1960s ...

Plate tectonics churns the icy exterior of Jupiter’s moon Europa, researchers report September 7 in Nature Geoscience. The finding marks the first evidence of plate tectonics elsewhere in the universe ...

A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...

(CBS News) A new study suggests that two recent earthquakes may indicate a literal seismic shift in our understanding of tectonic plate movements. Massive earthquakes under the Indian Ocean that took ...

Craig O'Neill receives funding from the ARC. Plate tectonics may be a phase in the evolution of planets that has implications for the habitability of exoplanets, according to new research published ...

Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. Scientists have assumed that the ...

Plate tectonics is a theory of geology developed to explain the phenomenon of continental drift and is currently the theory accepted by the vast majority of scientists working in this area. In the ...
