  1. they can be seen gliding around because of the wind moving in circles, and pushing the birds in circles, so the birds dont have to flap their wings.

  2. My answer is that the air moves in circles, therefore making it possible to glide/fly without flapping its wings

  3. The birds can glide without flappin their wings because the constant movement of the circular air currents underneath them let the birds wings carry them on top of the current.Because the air circulates in a circle the birds glide in a circle.

  4. The birds can float because the warm air pushes them up.

  5. My answer is that birds can glide around the sky without flapping there wings because the air moves in circles. This makes it possible for them to fly in the sky without flapping there wings

  7. According to my calculations, the bird can glide without flapping their wings because the air moves in a convection current pattern. When that happens,the warm air rises and the cool air falls making a circular pattern. Therefor, the birds can glide on top of the currents and stay in the air without flapping their wings.

  8. The birds can fly without flapping their wings because hot air rises and cold air falls, forming a circular motion. If the birds can catch the air current, they can fly in the circle by gliding.

  9. the bird can fly because the hot air goes up and the cold air goes down.

  10. birds can fly with out flaping their wings because air moves in a circular pattern.the cold air sinks and the warm air rises.

  11. Birds have the ablity to glide in the air without flapping their wings because air travels in a cirular motion traveling upward and downward. Hot air travels upward and cold air travels downward, and it repeats itself because hot air is less dense than warm air. The circular motion allows the bird to glide.

  12. The birds can fly without flapping their wings because hot air rises and cold air falls making a circular motion that keeps repeating

  13. Birds can go for a long time without flaping their wings because warm air rises and cold air decends and this repeats in a circular pattern, which allows the bird to go longer without flapping it's wings.

  14. Due to the air warming and cooling, a convection current forms in a circular pattern. The birds are able to effortlessly guide on the air because it is rising and basically carrying them.The circular pattern of the convection current leads to the birds gliding atop the air in a circle.
