Figure 1This diagram illustrates how sunlight is spread over a greater area in the polar regions. In addition to the density of incident light, the dissipation of light in the atmosphere is greater when it falls at a shallow angle. | | polar | dissipation | atmosphere | Figure 3This is a diagram of the seasons.  Regardless of the time of day (i.e. the Earth's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter. | | Earth | North Pole | South Pole | arctic winter | angle | sunlight | season | axis | summer | winter | day length | season | Figure 2One sunbeam one mile wide shines on the ground at a 90° angle, and another at a 30° angle.  The one at a shallower angle covers twice as much area with the same amount of light energy. | | angle | Northern | equator | Trigonometry | sine | noon | atmosphere | Heat energy | Radiant energy | energy level | Concrete | tar | metals | Axial tilt | Declination | 2008 | 06-28 | Categories | Climate | Seasons | Atmospheric radiation |
