  • Near the poles, the Sun’s rays strike the surface at a slant.

  • The more focused the rays are, the more energy an area receives.
  • The difference in solar energy received at different latitudes drives atmospheric circulation.
  • Warm air rise, and cool air sinks.
  • Places that get more solar energy have more heat.
  • places that get less solarenergy have less heat.
