What causes hot air to rise from the pavement on a hot summer day? a convection b conduction c radiation d insulation

a) Convection

During a hot summer day, the sun heats up the pavement. This causes the air in contact with the pavement to heat up as well. Hot air is less dense than cold air, so it rises. As the hot air rises, it creates a convection current, causing the shimmering effect that we see as hot air rising from the pavement.
