Fill in the Blanks W=H2O - The Water CycleOnline version What do you know about the water cycle. Fill in the gaps. by Marcin Pasnikowski 1 climate solid precipitation fresh evaporates erosion below atmosphere hydrological condenses The water cycle , also known as the cycle or the H2O cycle , describes the continuous movement of water on , above and the surface of the Earth . The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice , water , saline water and atmospheric water might be different . The water moves from one reservoir to another , such as from river to ocean , or from the ocean to the , by physical processes . The water cycle describes how water from the surface of the earth , rises into the atmosphere , cools and into rain or snow in clouds , and falls again to the surface as . In doing so , the water goes through different phases : liquid , ( ice ) and vapor . The water cycle involves the exchange of energy , 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 . The evaporative phase of the cycle purifies water which then replenishes the land with freshwater . The flow of liquid water and ice transports minerals across the globe . It is also involved in reshaping the geological features of the Earth , through processes including and sedimentation . The water cycle is also essential for the maintenance of most life and ecosystems on the planet .
