The energy of incident solar radiation reaching the surface of the earth declines toward the poles from its maximum in equatorial regions. One cause of this phenomenon is greater absorption of solar energy by the earth's atmosphere at high latitudes. Why is this?

  1. Cold air absorbs more solar radiation than warm air
  2. The earth's atmosphere is thicker at higher latitudes
  3. Solar radiation travels a longer path through the earth's atmosphere at higher latitudes
  4. Smoke and other particulates accumulate at higher latitudes, making the atmosphere more absorptive
