It is known that the Earth's magnetic field is produced by convection currents of an electrically conducting iron-nickel alloyin the liquid core, about 3,000 kilometers below the earth's surface.

Until now, the answer was thought to be unrest in Earth’s mantle. Under intense heat and pressure, superheated magma rises in what are known as convection currents, pushing the tectonic plates ...

While there may be convection currents in the mantle of a planet or moon below its lithosphere, these currents do not provide enough stress to break or drag the lithosphere along with them in a ...

New simulations reveal a hidden “ocean of fire” that once existed above Earth’s core, influencing the planet’s internal landscape. These ancient molten seas, known as the basal magma ocean, were a ...

They are thought to move around by convection currents in the mantle, but whether those currents exist in the whole mantle or just the upper part is still an open question, Murthy said.

Here convection currents push mantle material together, forming plumes of less dense rock that eventually will start rising and heating up regions of the mantle.

New research has uncovered a fascinating link between volcanic eruptions and mysterious structures deep within Earth’s interior, challenging long-standing assumptions about the planet’s lower mantle.

Gigantic hidden fortresses discovered 1,800 miles underground in Earth's mantle, rewrite how the planet's interior works.

They are thought to move around by convection currents in the mantle, but whether those currents exist in the whole mantle or just the upper part is still an open question, Murthy said.

The mantle, hidden far below your feet, moves and changes over time in ways we’re only starting to understand. With new tools like full-waveform inversion, scientists can now see parts of Earth ...

Many geophysicists believe that this cyclical pattern could be related to regular disruptions in the convection currents in the Earth’s mantle, upon which the continents float. However, scientists ...

This is the point of view adopted by scientists who regard the solid Earth as a single system. According to their simulations, the surface mainly drives the mantle, although changes occur over time.
