Scientists believed that Venus' crust was continuously thickening, in the absence of mechanisms like plate tectonics. However ...

Plate tectonics (from the Late Latin tectonicus, from the "pertaining to building") is a scientific theory that describes the large-scale motion of Earth's lithosphere. This theoretical model ...

"Plate tectonics as we know it on Earth today is not a good model for understanding processes in the Earth's earliest history," Naeraa said. His team's findings were published May 31 in the ...

The new model suggests that the force pulling the ... it opens the door for further exploration of the relationship between plate tectonics, volcanic activity, and seismic events in the Pacific ...

Our carbon model shows these processes alone cannot explain global cooling in the Cenozoic Era. The effects of rock erosion, not shown here, played a key role. Arrows indicate plate motion speed.

The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere.
