Worldwide circulation of water molecules, powered by the sun. Water evaporates from oceans, lakes, rivers, and, in smaller amounts, soil surfaces and bodies of organisms; water returns to the Earth in the form of rain and snow. Of the water falling on land, some flows into rivers that pour water back into the oceans and some percolates down through the soil until it reaches a zone where all pores and cracks in the rock are filled with water (groundwater); the deep groundwater eventually reaches the oceans, completing the cycle.
The movement of water from the earth to the atmosphere and back by evaporation and condensation.
The process by which water circulates on earth, through precipitation (rain or snowfall), runoff, use by plants and animals, percolation to groundwater, and evaporation.
The recycling and reutilization of water on Earth, including atmospheric, surface, and underground phases and biological and nonbiological components.
The movement of water between the atmosphere, ground and surface water bodies through the processes of evaporation, precipitation, infiltration, percolation, transpiration and runoff. Also known as the "hydrologic cycle".
the natural cycle of water in the environment
The cycle of water through the environment including rain, flow over and under the land and transpiration back into the atmosphere
The process by which water is transpired and evaporated from the land and water, condensed in the clouds, and precipitated out onto the earth once again to replenish the water in the bodies of water on the earth. See The Water Cycle
The circuit of water movement from the oceans to the atmosphere, to the Earth and back to the sea. Water moves through the cycle via processes such as precipitation, interception, runoff, infiltration, percolation, storage, evaporation and transportation.
the process by which water circulates through the ecosystem. Water enters the ecosystem by water vapors produced by plants and animals, as it rises, cools and condenses, it forms clouds that then produce rain, bringing the water back to the earth surface for consumption by plants and animals.
a continuous movement of water from the oceans up through the air to the clouds in the form of vapor, down to land or water as rain or snow, then back to the oceans through streams and rivers
The continuous movement of water, from Earth to atmosphere and back again.
The continuous recycling of water on earth through evaporation, condensation, and precipitation
Also known as the hydrologic cycle, it is the continual flow of water from the ocean to the atmosphere to the land and, after several delays, back to the ocean again.
The name to describe the way water is recycled in nature. Water falls as rain or snow and then flows into rivers or lakes and some into the oceans. Water returns to the air through evaporation and falls again as precipitation. Also known as the Hydrologic Cycle.
The path water takes through it's various states - vapor, liquid and solid - as it moves throughout the Earth's systems (oceans, atmosphere, ground water, streams, etc.). Also known as the hydrologic cycle. Click here for an animated presentation.
the cycle of water from groundwater, to stream, to river, to ocean, to clouds (by evaporation), to rain, and back to groundwater.
The recycling of water between the earth and the atmosphere
the hydrologic cycle in which precipitation (rain and snow) falls on land or on water bodies such as oceans, lakes, and streams. Some of the water evaporates or is taken up by plants and some of it percolates into the soil and eventually reaches lakes or the ocean (where water also evaporates). Plants give up moisture through evapotranspiration. (Humans and other animals also take up water, later releasing it as perspiration or waste.) Evaporation adds humidity to the atmosphere, eventually leading to precipitation again.
The water cycle is the movement of water from the surface of bodies of water, to the atmosphere, to precipitation. Water vapour enters the atmosphere by evaporation from surface bodies of water and from plants and trees. When the air becomes saturated, excess water vapour is released as condensation. This condensation is the source of all clouds and precipitation. The cycle of evaporation, condensation and precipitation is called the water cycle of the earth and atmosphere.
(hydrologic cycle) the continuous circulation of water from the atmosphere to the earth and back to the atmosphere including condensation, precipitation, runoff, groundwater, evaporation, and transpiration
Transition and movement of water involving evaporation, transpiration, condensation, precipitation, percolation, runoff, and storage.
The paths water takes through its various states - vapour, liquid, solid - as it moves throughout the ocean, atmosphere, groundwater, streams, etc.
The continuous cycling of water between the earth and the sky. Jump to Top
continuous movement of water from the oceans and fresh water sources to the air and land and then back to the oceans.
The continuous process of surface water (puddles, lakes, oceans) evaporating from the sun's heat to become water vapor (gas) in the atmosphere. Water condenses into clouds and then falls back to earth as rain or snow (precipitation). Some precipitation soaks into the ground (percolation) to replenish groundwater supplies in underground aquifers.
The cycle of which water travels when being used over again.
The process by which water keeps getting used over and over again. Very basically, water cycles from the ocean up into the sky. The clouds then travel over land where they drop their load of water which flows back to the sea.
The flow and distribution of water from the sky, to the Earth's surface, through various routes on or in the Earth, and back to the atmosphere. The main components are precipitation, infiltration, surface runoff, evapotranspiration, channel and depression storage, and groundwater.
The movement of water from the atmosphere to the earth and back to the atmosphere through precipitation, runoff, infiltration, percolation, storage, evaporation, and transpiration.
The never-ending movement of water between the sea, the land and the air.
the continual movement of water from the atmosphere to the earth and from the earth to the atmosphere
The process by which water cycles through the ecosystem. Water evaporating from oceans, plants, and soil forms clouds and returns to the surface as rain. This water recharges ground water, fills rivers, and eventually returns to the sea. When the water cycle is healthy, rain soaks into soils where it either remains available to plants in the root zone, or recharges groundwater that feeds wells, seeps, springs, and streams. Where the water cycle is unhealthy, rain generally runs off the land, causing flash floods, or evaporates from bare soil. In some areas of Australia it sinks in too fast and raises the water table, bringing salt into the root zone.

The continuous circulation of water from the atmosphere to the earth, including the ocean, and back to the atmosphere through condensation, precipitation, evaporation, and transpiration.
The cycle in which Earth's water moves through the environment.
the process in which water evaporated from rivers, lakes, and oceans rises and condenses into clouds, and then falls back to earth as rain, hail, sleet, or snow.
the movement of water from the air to and below the Earth's surface and back into the air
A never ending cycle by which water passes from the oceans to the clouds back to the Earth and into the oceans again
The path that water follows as it evaporates into the air, condenses into clouds, and returns to Earth as rain, snow, sleet, or hail. After the sun's heat dried up the pond, water from rain filled it back up, completing its journey through the water cycle.
The continuous circulation of water in systems throughout the planet, involving condensation, precipitation, runoff, evaporation and transpiration.
The circulation of water on Earth as it evaporates from the sea and lakes, condenses into clouds and falls again as precipitation (rain, hail, sleet, snow).
Movement of water from the air to land and water and back to the air. Evaporation, transpiration, condensation, infiltration, and runoff are all parts of the water (hydrologic) cycle.
The warmer the atmosphere, the more evaporation of water that takes. The more evaporation that takes place leads to warmer weather, so it is a feedback system that will mean changes in our weather patterns and continue to cause greater temperatures and greater evaporation.
the circuit of water movement from the oceans to the atmosphere and to the Earth and return to the atmosphere through various stages or processes such as precipitation, interception, runoff, infiltration, percolation, storage, evaporation, and transportation.
A biogeochemical cycle in which water is used, collected, distributed, and exchanged between organisms and Earth's environment.
is a circulation in which water moves between the atmosphere and the earth's surface
The fate of water from the time it leaves the atmosphere as precipitation until the water has been returned to the atmosphere by evaporation or plant transpiration. Soil plays a very important role in the water cycle, because a substantial portion of the precipitation reaching the earth falls on soil. The condition or quality of the soil determines such things as how much water runs off to rivers or lakes, how much enters the soil and can be taken up by plants or evaporated, and the rate and the amount of water that moves through the soil to groundwater.
the process of water moving from the earth into the atmosphere and back to earth again
The constant cycle by which water moves through the Earth’s environment, converting from liquid to gas vapor to liquid again through the processes of condensation and evaporation (e.g., water evaporates from the ocean into the air, then condenses to rain and falls back to the earth, where it runs off into the ocean again)
The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the Earth's surface to the sky and back again.
A friendlier term for "hydrologic cycle."

The cycling of water on Earth as it evaporates from the oceans, condenses into clouds, falls as rain and returns to the oceans.
The vertical and horizontal transport of water in all its states between the earth, the atmosphere, and the seas.
the cycle by which water evaporates from oceans, lakes, and other bodies of water, forms clouds, and is returned to those bodies of water in the form of rain and snow, the runoff from rain and snow, and ground water. [AHDOS
The water cycle — technically known as the hydrological cycle — is the continuous circulation of water within the Earth's hydrosphere, and is driven by solar radiation. This includes the atmosphere, land, surface water and groundwater. As water moves through the cycle, it changes state between liquid, solid, and gas phases.
