What is the term for the cycle in which water evaporates and returns to the earth?

The hydrologic cycle, also known as the water cycle, is the process by which water circulates through the environment. This cycle involves various stages including evaporation, condensation, precipitation, and runoff. When water evaporates from bodies of water like oceans, lakes, and rivers, it transforms into water vapor. This vapor then condenses in the atmosphere to form clouds, which eventually leads to precipitation in the form of rain or snow, returning the water to the earth.

This continuous movement of water is essential for replenishing freshwater supplies and sustaining ecosystems. Unlike other cycles listed, such as the nitrogen, carbon, and oxygen cycles, which deal with the movement of those specific elements and compounds in the environment, the hydrologic cycle is uniquely focused on the movement and transformation of water itself. Understanding this cycle is crucial for water management and conservation efforts, especially in the context of climate change and its effects on water resources.
