水循环系统(WaterCycleSystem)水循环系统是地球上水分子在不同形态之间持续运动和转化的自然过程。它包括蒸发、凝结、降水和径流等关键环节。通过这一系统，水从地表和海洋蒸发，形成云层，最终以降水的形式返回地面，维持生态平衡和人类用水需求。TheWaterCycleSystemisacontinuousnaturalprocessinwhichwatermoleculesmoveandtransformbetweendifferentstates.Itincludeskeystagessuchasevaporation,condensation,precipitation,andrunoff.Throughthissystem,waterevaporatesfromthesurfaceandoceans,formsclouds,andeventuallyreturnstothegroundasprecipitation,sustainingecologicalbalanceandhumanwaterneeds.
