A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have questions, though.

The surprise discovery of earth’s core composition may debunk previous assumptions on the solidity of the planet.

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 ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

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 ...

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 ...

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 ...
