The circulation of water through this system is described by the hydrologic cycle. 水在這個(gè)體系中的循環(huán)是用水循環(huán)來(lái)描述的。
Scientists now believe Titan has a hydrological cycle similar to Earth. 科學(xué)家們現在認為提坦的水循環(huán)和地球相似。
As we have already noted, the movement of water into the ground is part of the hydrologic cycle. 我們已經(jīng)說(shuō)過(guò)，水向地下運動(dòng)是水文循環(huán)的一部分。
Many scenarios for global warming, for example, invoke a speedup in the hydrological cycle by which water evaporates and then comes down as rain. 例如，全球氣候變暖的許多現象引起了水文循環(huán)的加速，其形式是水分的蒸發(fā)上升，然后以雨的形式降落至地面。
