WebConduction, radiation, and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

WebIn the most basic term convection is the transfer of heat from a high temperature object to a low temperature object. According to scientiﬁc laws heat cannot pass from a cold object to a warm object. Convection takes place because heated materials rise because of their lower density and cool materials fall.
