Which term describes the movement of water around the river system, including processes such as evaporation and precipitation?

• A. Transportation
• B. Hydrological Cycle
• C. Weathering
• D. Tributary

Answer: (B)

The movement of water around a river system, including evaporation and precipitation, is described by the hydrological cycle. This idea captures how water moves between sea, air, soil, groundwater, and rivers: evaporation lifts water into the atmosphere, moisture returns as precipitation, some water infiltrates the ground to become groundwater, and surface runoff and river flow transport water across the landscape, while plants contribute through transpiration. This cycle explains why rivers are continually fed and recharged by processes linked to the wider drainage basin. The other terms don’t describe this whole system: weathering is the breakdown of rocks, not the movement of water; a tributary is simply a smaller stream that joins a larger river; and transportation refers to the movement of materials or, in some contexts, a misused term for part of the water cycle, but not the cycle itself.
