For 10 points, name this transfer of heat by the circulation of a fluid that is used in certain types of ovens.
This process occurs in cells co-named for Benard that form hexagonal patterns. This process occurs when the Rayleigh number reaches a high value. Seafloor spreading is caused by its namesake currents in a portion of the upper mantle known as the asthenosphere. The natural type of this process is caused by temperature gradients that lead to differences in density. The ratio of this process to conduction is given by the Nusselt number.
