The water cycle

The water cycle The water cycle describes how water evaporates, forms clouds, is transported by wind and returned to Earth as rain, snow and condensation. The study of natural water is called ‘hydrology’. Hydrology describes how water flows from higher regions to lakes and the sea. This happens above ground, in streams and rivers, as well as underground. Did you know that there are underground rivers, called aquifers ?
