What are convection currents in Earth's magma?

Convection currents create the movement of Earth's tectonic plates in the magma.

Explanation:

Heat from the core and the mantle itself causes convection currents in the mantle. This flow, called mantle (magma) convection, is an important method of heat transport within the Earth. Mantle (magma) convection is the driving mechanism for plate tectonics

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
