The Water Cycle
The water cycle, also called the hydrological cycle, is the continuous movement of water above, on and below the surface of the Earth. The balance of water has remained constant over time, which means that the rain which fell on the dinosaurs is the same water you drink. The water travels from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, or from the atmosphere to the surface. In doing so, the water goes through all three phases (solid ice, liquid water, gaseous vapor) by the processes of condensation, precipitation and evaporation. The hydrologic cycle involves the exchange of heat which influences temperature changes. By transferring water from one reservoir to another, the water is constantly purified and Earth’s surface constantly replenished.
Basics of the water cycle include the process of condensation: when water vapor condenses into liquid and becomes precipitation in the form of rain, sleet, hail, and snow. Evaporation is the process by which liquid water becomes vapor as it moves from the surface into the atmosphere. Plants also produce water via the process of transpiration. Approximately 10% of the water in the atmosphere comes from transpiration.
