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.

What is Convection? When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection.

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.

Small magnetic waves discovered in Earth’s core could help illuminate what is going on deep inside our planet. Earth’s core has a solid inner layer and an outer layer made of liquid metal.

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 ...

This means convection could easily occur, even at the extremely low temperatures of Pluto, which average more than 300 degrees Fahrenheit below zero. A team led by William McKinnon, deputy lead of the ...

Data show the polygons are 20 to 30 kilometers in diameter. Only the tips of the water icebergs can be seen, and the team performed calculations as if they were spheres, a regular shape that requires ...
