• The Gulf Stream illustrates the transference of heat by convection. 伯莎M.克拉克. 科学通论.
• 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. 伯莎M.克拉克. 科学通论.
• Convection is responsible for winds and ocean currents, for land and sea breezes, and other daily phenomena. 伯莎M.克拉克. 科学通论.
• When a liquid or a gas moves away from a hot object, carrying heat with it, the process is called _convection_. 伯莎M.克拉克. 科学通论.
