Víz körforgásba, also known as the water cycle or hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. This essential process is driven by solar energy and gravity. The cycle begins with evaporation, where water from oceans, lakes, rivers, and other bodies of water turns into vapor and rises into the atmosphere. Plants also contribute through transpiration, releasing water vapor from their leaves. As this water vapor rises, it cools and condenses, forming clouds. Precipitation then occurs when water in the clouds falls back to Earth in the form of rain, snow, sleet, or hail. Once on the ground, water can follow several paths. It can infiltrate into the soil, becoming groundwater. It can flow over the surface as runoff, eventually returning to rivers, lakes, and oceans. Water can also be stored in ice caps and glaciers. This journey repeats indefinitely, ensuring the availability of freshwater and influencing weather patterns and climate across the globe. The water cycle is vital for all living organisms and sustains ecosystems.
