  1. Birds are able to glide over parking lots on sunny days because they use the air which is heated from the sun's reflection upon the pavement against the bottom of their wings in order to fly in the sky without effort.

  2. The reason why the birds can glide over the parking lot like that is becuase the hot air is less danse causing it to rise, which makes the birds use less effort when flying.

  3. Birds are able to glide over the parking lot like that is because the sun heats the air and makes it less dense. The less dense air rises which allows the birds to stay in the air with little to no effort.
