本题详细解析:
The hydrological cycle is driven by the sun. Energy frg1dbc0(jw. 1tvcah-nmwrl (r0x 7 -qhom the sun leads to the evaporation of water which is followed by clouds, precipitation, runoff and the remaining flows of the water cycle. The moon does not play a role in the hydrological cycle flows, but it does have an effect on the tidal flow. Similarly wind can change the movement of water throughout the cycle but does not act as the driving force. Waves on the other hand are a result of the aforementioned forces (moon and wind).
