Question map
Which one of the following statements regarding water cycle is correct ?
Explanation
The water cycle is a continuous exchange of moisture between the atmosphere, land, and oceans [6]. Statement 4 is correct because surface water and groundwater are manifestations of a single integrated resource; they are interconnected through processes like infiltration and discharge [5]. Groundwater can move into surface water bodies, and conversely, surface water can move into the subsurface [3]. Statement 1 is incorrect as transpiration by plants contributes approximately 10% of atmospheric moisture, which is essential for cloud formation [4]. Statement 2 is incorrect because evapotranspiration (the sum of evaporation and transpiration) and sublimation both contribute to cloud formation [2]. Statement 3 is incorrect because precipitation is the primary source of freshwater that recharges groundwater through infiltration and percolation into the saturated zone [6].
