Water cycling, also known as the hydrological cycle or hydrologic cycle, is the continuous movement of water between the atmosphere, land, and oceans. This cycle involves processes such as evaporation, condensation, precipitation, infiltration, and runoff. Water cycling plays a critical role in regulating the Earth's climate and distributing water resources around the planet. Understanding and monitoring water cycling is important for managing water resources, predicting weather patterns, and studying the impacts of climate change. Researchers in this area use a variety of tools and techniques to study and model the complex interactions that govern the movement of water through the Earth's ecosystems.
