Quizplus · Accepted Answer

Processing of salt water to freshwater (desalination) has a relatively minor impact on the global water cycle compared to the other options listed. While it does involve the removal of salt from seawater to produce freshwater, its scale and impact on the overall water cycle are less significant compared to the extensive changes in land use and water consumption associated with increased asphalt and concrete surfaces, conversion of natural landscapes into agricultural fields, and the expansion of irrigated agriculture. These activities alter evaporation rates, groundwater recharge, and runoff patterns on a much larger scale.
