Chapter 4 Answers to Questions for Review 1. Within the atmosphere, there is an unending circulation of water. Since the oceans occupy over 70 percent of the earth’s surface, we can think of this circulation as beginning over the ocean. Here, the sun’s energy transforms enormous quantities of liquid water into water vapor in a process called evaporation. Winds then transport the moist air to other regions, where the water vapor changes back into liquid, forming clouds, in a process called condensation. Under certain conditions, the liquid (or solid) cloud particles may grow in size and fall to the surface as precipitation—rain, snow, or hail. If the precipitation falls into an ocean, the water is ready to begin its cycle again. If, on the other hand, the precipitation falls on a continent, a great deal of the water returns to the ocean in a complex journey. 2. Condensation is the transformation of water vapor into liquid, forming clouds. Under certain conditions, the liquid (or solid) cloud particles may grow in size and fall to the surface as precipitation— rain, snow, or hail. 3. Condensation nuclei are microscopic bits of dust, smoke, and salt from ocean spray that serve as surfaces on which water vapor may condense. These nuclei allow condensation to occur, clouds to form, and therefore assist in the generation of precipitation. 4
