Convection currents are generated in the earth’s inner mantle as molten rock forms from the radioactive decay of elements. As hot gas and liquid is produced it moves upward, displacing the ...

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.

Earth’s core has a solid inner layer and an outer layer made of liquid metal. The difference in temperature between the hot centre and cooler exterior layer drives convection currents in the ...

When an electric current passes through a metal wire ... This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field.

“The way they have collected suggests they have moved or floated like icebergs with the convection current. If this is true ... a regular shape that requires the shallowest volume of liquid to float, ...

Convection currents can be seen in lava lamps. The wax inside the lamp warms up, becomes less dense than the liquid and so rises. When it rises, it cools and becomes denser again, so it sinks.

The crust of volcanically active Venus could be churning with convection currents just like the ... tectonics—as well as within our planet's liquid outer core. At just some 25 miles thick ...

Video: Small balls in a tank of viscous liquid reveal that insulating ... disrupting or destroying existing convection cells. As a new system of currents gets going, the mantle wells up and ...

As these materials solidify, heat is released and causes upward movement in the liquid layer – what’s known as a convection current. In turn, this convection generates our planet’s ...

Drying drops exhibit a rich phenomenology that depends on the suspended materials, convection and evaporation 1, surface tension and capillary interactions 2, contact line pinning and depinning 3 ...
