The three correct answers for how heat energy leaves the surface of land masses are:
-
Evaporation - Heat energy is used to convert water from liquid to vapor, resulting in a loss of heat from the surface.
-
Radiation of infrared energy - Land masses emit heat in the form of infrared radiation, losing energy to the atmosphere.
-
Conduction to air, which then rises in convection - Heat can conduct from the land surface to the air above it, and warmer air can rise, transferring heat away from the surface.
Therefore, the correct responses are evaporation, radiation of infrared energy, and conduction to air, which then rises in convection.
