Rhythmic pulses of molten rock are rising beneath eastern Africa, according to a new study. The pulsing plume of hot mantle beneath Ethiopia, driven by plate tectonics, is slowly pulling the region ...

The supervolcano lurking under Yellowstone National Park may not have resulted from a rising plume of hot rock from the planet’s depths as previously suggested. New simulations of North America’s ...

Scientists have discovered an ancient "ghost" plume lurking beneath Oman. The magma plume is trapped beneath a thick portion of Earth's crust and the upper part of the mantle, the planet's middle ...

Why this happens is unclear, but the MIT team says that two of the determining factors are the speed of the tectonic plate and the size of the seabed swell caused by the plume. Based on a study of 14 ...

"Knowing what a chicken looks like and what all the chickens before it looked like doesn't help us to understand the egg," says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to ...

Bringing fresh insight into long-standing debates about how powerful geological forces shape the planet, from earthquake ruptures to mountain formations, scientists at Scripps Institution of ...

Artist's impression of an active mantle plume – a large blob of warm and buoyant rock – rising from deep inside Mars and pushing up Elysium Planitia, a plain within the planet's northern lowlands.

12.11.2015: Our planet Earth is the only planet in the Solar System that possesses Plate Tectonics. The Earth's surface is in a constant state of change; the tectonic plates together with the oceans ...

It is common knowledge that the Earth's rigid upper layer called lithosphere is composed of moving plates. But just what mechanism first set plate tectonics into motion still remains a mystery.
