Hot air rises from pavement on a hot summer day due to the principle of convection. When the pavement is heated by the sun, it warms the air immediately above it. Hot air is less dense than cooler air, causing it to rise. As the hot air rises, cooler air moves in to take its place, creating a convection current. This phenomenon can often be observed as shimmering waves or distortions in the air above hot surfaces.
