This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

one gives way and sinks into the hot mantle and ends up in a sort of plate graveyard on top of Earth's metallic core. "Our new results suggest that for most of Earth's history, convection in the ...

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Convection in a liquid Convection in a liquid can be seen ...

geoscientists have been debating whether convection extends from the surface to the core–mantle boundary, or whether the mantle is compositionally and dynamically layered. Geochemical ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...
