Water cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. The total amount of water remains essentially constant.
Water cycle, also known as the hydrologic cycle, involves a series of stages that show the continuous movement and interchange of water between its three phases – solid, liquid, and gas, in the earth’s atmosphere. The sun acts as the primary source of energy that powers the water cycle on earth. Bernard Palissy discovered the modern theory ...
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. Water Cycle Diagram During this process, water changes its state from one phase to another, but the total number of water particles remains the same.
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. Water vapor surrounds us, as an important part of the air we breathe.
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere ...
Water cycle showing human influences and major pools (storages) and fluxes. [19] The water cycle describes the processes that drive the movement of water throughout the hydrosphere. However, much more water is "in storage" (or in "pools") for long periods of time than is actually moving through the cycle.
Water availability also depends on when and how fast water moves (water timing) through the water cycle. Finally, water availability depends on how clean the water is (water quality). By understanding human impacts on the water cycle, we can work toward using water sustainably. Read more about the components of the water cycle in more detail:
The hydrologic cycle involves the continuous circulation of water in the Earth-Atmosphere system. At its core, the water cycle is the motion of the water from the ground to the atmosphere and back again. Of the many processes involved in the hydrologic cycle, the most important are: evaporation; transpiration; condensation; precipitation ...
The water cycle describes where water is on Earth and how it moves. Human water use, land use, and climate change all impact the water cycle. By understanding these impacts, we can work toward using water sustainably.
The water cycle is the endless process that connects all of that water. It joins Earth’s oceans, land, and atmosphere. Earth’s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. The rain came from water vapor that escaped the magma in Earth’s molten core into the atmosphere. Energy from ...
NASA & The Water Cycle. Water is an integral part of life on this planet, and NASA plays a major role at the forefront of water cycle research. Currently, there are many NASA missions that are simultaneously measuring a myriad of Earth's water cycle variables; Evaporation, Condensation, Precipitation, Groundwater Flow, Ice Accumulation and Runoff.
The water cycle consists of several interconnected steps or processes: Evaporation: Evaporation is water transitioning from a liquid to a gas (water vapor) due to heat energy from the sun. Most evaporation occurs from the surface of oceans and seas, but it also happens from lakes, rivers, and soil.
The most basic step of the water cycle is the change of state of water as a liquid, gas or solid in the atmosphere. However, the water cycle also envelops various methods of water transportation and water types such as plant uptake, transpiration, groundwater, precipitation, and percolation.

Earth's water is always in motion, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.
Water from plants and trees also enters the atmosphere. This is called transpiration. Warm water vapor rises up through Earth’s atmosphere. As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. This process is called condensation.
The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This gigantic system, powered by energy from the Sun, is a continuous exchange of moisture between the oceans, the atmosphere, and the land.
The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life. Learn more about Earth's water cycle on the Precipitation Education website.
At its most basic, the water cycle is how water continuously moves from the ground to the atmosphere and back again. As it moves through this cycle, it changes forms. Water is the only substance that naturally exists in three states on Earth – solid, liquid, and gas. Over 96% of total global water is in the ocean, so let’s start there ...
A more efficient mechanism for producing a precipitation-sized drop, is a process which leads to the rapid growth of ice crystals at the expense of the water vapor present in a cloud. These crystals may fall as snow, or melt then fall as rain. This process is known as the Bergeron-Findeisen process. How much water falls during a storm?
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans, where it ...
