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.
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 water cycle or hydrologic cycle is a continuous biogeochemical process by which water circulates through the Earth’s atmosphere, surface, and underground environments. This cycle is essential for maintaining life on Earth, regulating climate, and shaping the planet’s ecosystems.
Learn how water moves above and below the surface of the earth with a neat labelled diagram of Water Cycle.
A detailed diagram depicting the global water cycle. The direction of movement of water between reservoirs tends towards upwards movement through evapotranspiration and downward movement through gravity. The diagram also shows how human water use impacts where water is stored and how it moves. [1]
The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three phases, and in many forms—as lakes and rivers , glaciers and ice sheets , oceans and seas, underground aquifers , and vapor in the air and clouds .
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 ...
Our newest diagram, released in 2022, depicts the global water cycle, as well as how human water use affects where water is stored, how it moves, and how clean it is. The diagram is available as a downloadable product in English, Spanish, and Simplified Chinese.
The water cycle impacts ecosystems, economies, and our daily lives. The resources in this collection help teachers guide their students beyond the classic water cycle diagram and through the complex social and environmental issues that surround water.
