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.
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.
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.
What are the major 4 steps in the water cycle? The major 4 steps are evaporation of water, then condensation, precipitation and collection. The sun evaporates water sources and contributes to the formation of water vapor.
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.
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 water cycle (or hydrologic cycle or hydrological cycle), is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
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.
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.
Learn more about where water is on Earth and how it moves using one of the USGS water cycle diagrams. We offer downloadable and interactive versions of the water cycle diagram for elementary students and beyond.
