The continuous flow of water between the Earth's surface and the atmosphere is called what?

• A. Hydrological cycle
• B. Water cycle
• C. Global water cycle
• D. Weather cycle

Answer: (C)

The continuous flow of water between the Earth's surface and the atmosphere is best described as the global water cycle. This term highlights that water moves through the entire planet—evaporating from oceans and land, transpirating from plants, condensing into clouds, precipitating back to surfaces, and then infiltrating, running off, and collecting in rivers, lakes, and groundwater. The cycle is ongoing and connects all parts of the Earth, from the atmosphere to oceans and land, with different stores and residence times. The word global emphasizes the planetary scale of this circulation, rather than focusing on a single location. The weather cycle isn’t the right label because weather refers to short-term atmospheric conditions, while the water cycle describes the long-term movement of water through the Earth–atmosphere system.
