Summer Solstice Animation
Figure 6h-7: This animation displays the geometric relationship that occurs between the Earth and the Sun during the summer solstice. The yellow line on the Earth represents the equator. The green lines are the Tropic of Cancer and Capricorn. The Arctic and Antarctic Circles are shown with red lines. In the animation, the North Pole is tilted 23.5° toward the Sun. This condition causes the Sun's rays to be most intense at the Tropic of Cancer (23.5° North). This is illustrated on the animation by the location sideways yellow T. For any location on the Tropic of Cancer, the Sun's position in the sky would be at 90° or directly overhead at solar noon. Also, note that all locations South of the Antarctic Circle (66.5° South) are in total darkness, while locations North of the Arctic Circle (66.5° North) receive 24 hours of daylight.
