what best summaries the below sentences Natural Geography, Prof. H. Jewsbury, 2005, Page 17. Water, known chemically as H2O, exists in three phases or states: solid, liquid and gas. The water cycle is the method by which the Earth’s water, in all its forms, is continuously recycled via natural processes. The main features of the cycle are: The evaporation of water upon exposure to heat from the sun; The condensation of water and the formation of clouds; The precipitation of water in the form of rain, snow, hail, and so on; The infiltration of water back into the rivers, seas and oceans in order for the cycle to repeat. Water plays a critical role in the life cycle. No other known planet possesses liquid water at its surface, and scientists deem this terrestrial quality to be one of the key reasons behind this planet’s abundance of flora and fauna.
