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 ...

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 ...

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 ...

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 ...

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 ...

Minerals suggest large blocks of Earth’s crust moved around as early as 3.2 billion years ago Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million ...

Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

BUFFALO, N.Y. — Margarete Jadamec, a University at Buffalo expert on Alaskan plate tectonics, is available to discuss the 7.0 earthquake in the Anchorage area, and how the region’s unique geology ...

There may be more habitable planets in the universe than we previously thought, according to geoscientists, who suggest that plate tectonics -- long assumed to be a requirement for suitable conditions ...

Volcanic rocks at island arcs can show characteristics of the subducting oceanic plate. The isotopic signature of rocks at the Izu-Bonin arc in the northwest Pacific suggest the presence of ...
