Question

The mechanism of hot matter rising and cool matter falling is caused by a change in what

factor?

Answer 1

Convection

Step-by-step explanation:

• Convection is the transfer of heat by the movement of molecules within solid, liquids, and gases. It includes advection and diffusion that is the transfer of energy or mass particle along a gradient.

• Convection takes place in a mantel that is a slow-motion of the movement of convection current that carries the heat form into the surfaces. The material that is dense is thermally contracted and sinks under its weight in the process.
