The four mechanisms of heat transfer are conduction, radiation, convection, and advection. An understanding of the various mechanisms of energy transfer is crucial in understanding weather, climate, evolution of landscapes, and many of our daily activities.
Match the following statements to the correct mechanism of heat transfer.

1) Least important mode of heat transfer in gases.
2) Capable of passing through a vacuum.
3) Vertical heat transfer by flow of a gas, a liquid, or a weak solid.
4) More important mode of heat transfer in solids.
5) Often responsible for coastal fog formation.
6) Thermal energy is transferred by direct contact.
7) Energy transfer by means of electrical and magnetic fields.
8) Conduction Horizontal transfer of heat.
9) Often takes the form of a circular path.
