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. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.

The answer is A. Air molecules that come into contact with the warmer land and surface of the oceans and lakes increase their thermal energy through conduction. Those molecules then heat up other air molecules through convection. In the winter, the land and water is cold, thus cooling the air.
