The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers ...

The activity of the solid Earth – for example, volcanoes in Java, earthquakes in Japan, etc – is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits ...

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 (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 builds ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Map of Earth's principal tectonic plates. Earth's lithosphere. Major and minor plates. arrows indicate direction of movement at ...

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 ...

Researchers have produced a new estimate for the origin of Earth's plate tectonics—the movement of large chunks of the planet's outer layer, or crust. Although there is broad consensus that plate ...
