What continuous process involves water moving through living and nonliving parts of the environment?

• A. Water cycle
• B. Hydrological loop
• C. Carbon cycle
• D. Nitrogen cycle

Answer: (A)

Water moving through both living organisms and nonliving parts of the environment is described by the water cycle. This is a continuous movement that connects the atmosphere, land, oceans, rivers, groundwater, and living beings. It starts with evaporation of water from oceans and soils, and plants also contribute through transpiration. The water then condenses into clouds and falls as precipitation, returning to the surface. From there, water infiltrates the soil, becomes groundwater, or runs off into rivers and lakes, and the cycle begins again. This process continually transports and redistributes water across the environment, involving both biotic components (plants, animals) and abiotic components (air, soil, rocks, bodies of water). The other cycles focus on different elements—carbon and nitrogen—moving through air, water, soil, and living things. They describe how those elements cycle through ecosystems, not the movement of water itself. The term hydrological loop is sometimes used to refer to similar ideas, but the standard and most commonly used term for this continuous water movement is the water cycle.
