I apologize for the repetition, my previous response was incorrect. The correct answer is actually "Due to conduction." When the sun heats up the pavement, the heat is transferred from the pavement to the air molecules in contact with it. These heated air molecules become less dense than the surrounding air and subsequently rise, creating the phenomenon of hot air rising from the pavement on a hot summer day.

The correct answer is "Due to convection."
Convection is the transfer of heat through the movement of a fluid (either a gas or a liquid). On a hot summer day, the pavement gets heated up by the sun. As a result, the air directly above the pavement becomes warmer. Warmer air is less dense than cooler air, so it becomes buoyant and rises. This rising motion of the warm air is what causes the phenomenon of hot air rising from the pavement.
To determine the answer to this question, you can use basic knowledge of heat transfer mechanisms. Insulation primarily helps in reducing heat transfer, but it does not explain the specific movement of hot air from the pavement. Conduction is the transfer of heat through direct contact, but it doesn't explain the upward movement of air. Radiation is the transfer of heat through electromagnetic waves, but it doesn't fully explain the phenomenon either. Only convection accurately describes the movement of hot air due to the temperature difference between the pavement and the surrounding air.
