what is the purpose of the hydrologic cycle

The purpose of the hydrologic cycle (or water cycle) is to continuously circulate water through the Earth's atmosphere, surface, and underground reservoirs, enabling the availability of water for all living organisms and maintaining ecosystems. It regulates weather patterns, redistributes heat, purifies water, transports minerals, and shapes geological features through processes like evaporation, condensation, precipitation, infiltration, and runoff. This cycle sustains life by replenishing freshwater supplies and supporting natural processes essential for growth, health, and environmental balance. Additionally, it plays a key role in transferring heat from the tropics to the poles, influencing global climate and weather systems
