10. Fig. 5-5, p. 82 (a) Rays of sunlight penetrate the lower atmosphere and warm the earth's surface. (b) The earth's surface absorbs much of the incoming solar radiation and degrades it to longer-wavelength infrared (IR) radiation, which rises into the lower atmosphere. Some of this IR radiation escapes into space as heat and some is absorbed by molecules of greenhouse gases and emitted as even longer wave-length IR radiation, which warms the lower atmosphere. (c) As concentrations of green-house gases rise, their molecules absorb and emit more infrared radiation, which adds more heat to the lower atmosphere. Natural Greenhouse Effect

11. Fig. 5-6, p. 82 Prevailing winds pick up moisture from an ocean. On the windward side of a mountain range, air rises, cools, and releases moisture. On the leeward side of the mountain range, air descends, warms, and releases little moisture. Rain Shadow Effect Dry habitats Moist habitats
