... cycle ( water cycle ) This is the movement of water and its transformation between the gaseous (vapour), liquid, and solid forms. The major processes are condensation by which precipitation is formed, movement and storage of water overland or underground, evaporation , and the horizontal transport of moisture. The length of time any water stays in the atmosphere is about eleven days. Hydrological ...

... cycle ( water cycle ) Circulation of through land, air, and sea. Water evaporates from the sea; most falls back into the oceans, but cloud carries some over land. There it falls as precipitation, and by surface run off or infiltration and seepage, it gradually finds its way back to the sea. Less than 1% of the world's water is involved in this cycle...

... cycle The transport of water in all its forms within and between the atmosphere, cryosphere , hydrosphere , and the Earth's surface. It is a closed cycle, although very small quantities of juvenile water may be added by volcanic action. There may also be some slight losses when water is dissociated in the upper atmosphere to hydrogen and oxygen, with some hydrogen being lost to...

...hydrological cycle ( water cycle ) The circulation of water between the atmosphere, land, and oceans on the earth. Water evaporates from the oceans and other water bodies on earth to form water vapour in the atmosphere. This may condense to form clouds and be returned to the earth’s surface as precipitation (e.g. rainfall, hail, and snow). Some of this precipitation is returned to the atmosphere directly through evaporation or transpiration by plants; some flows off the land surface as overland flow, eventually to be returned to the oceans via rivers; and...

...the hydrological cycle comprises one major input, six stores, seven transfer processes, and three outputs (Fig. 1). Fig. 1. The major components of the hydrological cycle. Catchment inputs; precipitation . Precipitation occurs in a variety of forms, including fog, drizzle, rain, sleet, hail, and snow. The most important input in high latitudes and at high altitudes is snow. Snow will often accumulate and can eventually compact to form glaciers and ice caps. In this case, the input is released slowly into the hydrological cycle and the output via...

... Cycle The Average Water Cycle Heated by the Sun's radiation, the ocean and land surface evaporate water that then moves around with winds in the atmosphere, condenses to form clouds, and falls back to the Earth's surface as rain or snow. Precipitation over land may be stored temporarily as snow or soil moisture, and it is the excess rainfall that runs off and forms streams and rivers that discharge the freshwater into the oceans. This then completes the global hydrological (water) cycle. Associated with this water cycle, energy, salt within the...

...the hydrological cycle Recharge is the process by which atmospheric water is added to groundwater in the hydrological cycle. The process entails the addition of water to the land surface by rainfall, melting of snow, or overland flow, followed by infiltration. The rate of recharge can be much smaller than the rate of infiltration because evaporation from shallow pores in the soil or transpiration by plants can return water to the atmosphere before it makes its way to the water-table. Recharge is one of the most difficult components of the hydrological cycle to...

...balance (Speidel and Agnew, 1988). Human Interactions with the Hydrologic Cycle The hydrologic cycle impacts upon human existence and behavior both directly through its influence on the disposition of water resources and indirectly through its inextricable meshing with the atmospheric circulation and with climate. In turn, humans have a powerful influence on the hydrologic cycle, modifying systems and changing flows and storages of water. Human dependence upon the components of the hydrologic cycle is absolute. Drinking water supplies are literally vital and...
