The water cycle is the continuous process of water moving from Earth's oceans, atmosphere and land. This cycle does not move in a particular order but in many different variations because different variables impact it like, topography, temperature and location.      Through precipitation, water condenses, forming a liquid and falling to the Earth as rain, snow, hail or fog. Once on the ground, water either remains in its liquid state, freezes, becoming ice or evaporates, or be...

The level of water in all lakes fluctuates, raising during years of higher amounts of rainfall and snowmelt and falling during periods of drought. The Environmental Protection Agency has been measuring the fluctuations of the Great Lakes, the largest natural lakes in the United States, since the 1860s. Similarly, water levels in reservoirs, human-made lakes, fluctuate because of evaporation, a lack of rainfall, water supply use, and water flow requirements. Levels tend to be relatively lower in ...
