We can’t get samples from either of them, so these conclusions are based on models of the way convection drives circulation within the mantle. The team thinks the fact the two LLVPs are on almost ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Two enormous continent-sized "islands" found buried deep inside the Earth's mantle are challenging ... they are not involved in the convection or flow of the mantle, meaning that the mantle ...

By combining a model of mantle convection, including a reconstruction of how tectonic plates have moved over the Earth's surface over the last billion years, the study has been able to show that ...

The Earth has a layered structure made ... Tectonic plates float on the semi-solid mantle, which moves very slowly as a result of convection currents driven by heat energy from the hot core.

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...
