Dynamic Earth presents the principles of convection in the earth's mantle in an accessible style. Mantle convection is the process underlying plate tectonics, volcanic hotspots and, hence, most ...

How plate tectonics works The driving force behind plate tectonics is convection in the mantle. Hot material near Earth's core rises, and colder mantle rock sinks. "It's kind of like a pot boiling ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

Here’s how it works. Earth's mantle is split by the Pacific Ring of Fire, an ancient schism that reflects the creation and destruction of the supercontinent Pangaea, a new study finds.

Known to be relatively stable portions of the Earth's continental crust, cratons have remained largely ... Additionally, a ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied.

A new study suggests the seismic energy traveled outward from a previously unmapped fault, emanating from the hypocenter in bouncing waves that shook distant areas Margherita Bassi Volcanic ...

Deep beneath our planet, two gargantuan, continent-size blobs of sizzling material rise from Earth’s hot, liquid outer core into its rock-filled mantle layer. Scientists can’t directly see ...

The idea that the Earth's crust and mantle might move together like a "conveyor belt" as a result of convection currents in the latter was first proposed in 1919 by the British geologist Sir ...

A mysterious find on Easter Island, investigated by a team of geologists, suggests that the Earth's mantle seems to behave differently than once thought. Geography textbooks describe the Earth's ...

Geology textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ...
