tells how convection currents in Earth's core generate the planet's magnetic field and relates the migration of Earth's magnetic north pole. looks at one theory of how the moon formed—a massive ...

Earth's solid surface, or lithosphere, extends more than a hundred miles into the planet. It's broken into large chunks, and the convection currents of molten rock below exert pressure on these ...

The new analysis provides an alternative to the hypothesis that the movement of tectonic plates is related to convection currents in the Earth's mantle. A study led by geophysicist Anne M.

On Earth, convection currents churn through the mantle (the layer that lies beneath the crust), causing tectonic plates to move around the planet's surface and triggering geological activity like ...

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

Early in the days of plate tectonic theory, geologists and geophysicists assumed plates move because of mantle convection. Currents of hot, molten material rising inside the Earth push the ...

Convection currents in the mantle move faster than previously predicted Ars Electronica/Flickr Convection currents in the Earth's mantle move faster than previously believed, say researchers.

The solidification of the outer core releases heat which drives convection currents in the outer core that helps to generate Earth's magnetic field. The swirling motion of the outer core generates ...

These polygons are formed by slow convection currents in a 4 km-thick layer of solid nitrogen ice. "Pluto is probably only the second planetary body in the solar system, other than Earth ...

The crust of volcanically active Venus could be churning with convection currents just like the Earth's mantle. This is the conclusion of researchers from the Washington University in St. Louis ...

They suggest that Earth, like the other rocky planets Mercury and Mars, is cooling and becoming inactive much faster than expected,” Murakami explains. However, he cannot say how long it will take, ...

leading to the greater cooling of the Earth. The study could rewrite what we already know about the dynamic processes leading to the slowing down of convection currents. "Our results could give us ...
