Describe how convection current forms?
Convection currents form when a subducting tectonic plate is pulled down into the mantle. The material is is then moved towards the mid-ocean ridge where the material will form new sea floor and...

Describe a convection current?
Convection currents are currents caused by the expansion of a liquid, solid, or gas as its temperature increases.while colder, denser material sinks.. Convection currents arise in the atmosphere...

Describe how convection currents form?
Convection is the movement of molecules within fluids (i.e. liquids, gases) and rheids. It cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in...

How does a convection current work?
When they get hotter, gasses and fluids have a lower density (they weigh less per cubic inch) so they rise above the cooler material. Another answer Most of the time a convection current happens...

How does a global convection cell work?
With all the heat under the crust into the mantle, the hot magma starts to move like any convection current so it goes up and then back around again to be reheated. at the top the convection current...
