The correct answer is due to convection.
As the sun heats the pavement, the air in contact with the pavement absorbs the heat and becomes warmer. Warm air is less dense than cold air, so it rises. This process creates a convection current, where the hot air near the pavement rises while cooler air moves in to take its place. This is why hot air appears to rise from the pavement on a hot summer day.
Why does hot air rise from pavement on a hot summer day?
due to conduction
due to radiation
due to convection
due to insulation
