) A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.

Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface.

A convection heat storage unit (CHS) system is similar to an ICS system, except the storage tank and collector are physically separated and transfer between the two is driven by convection.

Conduction, convection, and radiation all occur more rapidly over large thermal gradients.

This may be caused by the disappearance of a helium convection zone near the surface.

The occurrence of convection in the outer envelope of a main sequence star depends on the mass.

In the engineering sciences, heat transfer includes the processes of thermal radiation, convection, and sometimes mass transfer.

Within the context of a solar collector, convection and radiation are the most important sources of heat loss.

The convection between the relatively warm water and cold air in the winter plays an important role in the Arctic climate.

Most of the drying is done using microwaves to evaporate the water, but the final drying is done by convection heating, to avoid problems of arcing with metal pieces in the laundry.
