- In convection, air and water circulate freely, carrying heat with them; in conduction, heat flows from a warm region toward a cold region, but there is no apparent motion of any kind. Bertha M. Clark. General Science.
- Convection is responsible for winds and ocean currents, for land and sea breezes, and other daily phenomena. Bertha M. Clark. General Science.
