Describe the three mechanisms of heat transfer. Which mechanism is least important as a means of heat transfer in the atmosphere?

What will be an ideal response?


The three mechanisms of heat transfer are conduction (the transfer of heat through matter by molecular activity; this is the least significant), convection (the transfer of heat by mass movement or circulation within a substance), and radiation (the heat-transfer mechanism by which solar energy reaches our planet as radiant energy readily travels through the vacuum of space).
