The molecules vibrate and the electrons in the valence shell are easily knocked out of their shell, this energy is transferred between molecules from high a temperature area to low temperature area.
Convection happens when heat transfers through fluids (liquids and gases) by the upward movement of warmer, less dense regions of fluid.
Copper is a metal, which is a conductor.

The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
Convection is used whenever it is necessary to heat a pot of water on the stove.
