答案 The Water Cycle The water cycle describes the continuous movement of water / on, above and below the surface of the Earth. / Although the balance of water on Earth remains fairly constant over time, / individual water molecules can come and go, in and out of the atmosphere. / The water moves from one reservoir to another. / In so doing, the water goes through different phases: liquid, solid and gas. / The water cycle involves the exchange of heat, which leads to temperature changes. / For instance, when water evaporates, it takes up energy from its surroundings and cools the environment. / When it condenses, it releases energy and warms the environment. / These heat exchanges influence climate. /
