It is the circular path of water in its various phases that gives the hydrological cycle its term cycle. The cycle begins with evaporation (from the ocean say), follows through condensation as clouds...
The carbon cycle is the cycle in which carbon moves around...well, here's a "simple" description: Humans take in oxygen and change it to carbon dioxide. Burning things and the fire itself, also...
Water cycle: the sun's heat evaporates the water called evaporation. and then the evaporation turns into a cloud, called condensation. then once the cloud gets too heavy with water (that's why the...
