The lithosphere, biosphere, hydrosphere and atmosphere are all are part of the hydrologic cycle. The lithosphere is the rigid outer part of the earth, consisting of the crust and upper mantle. The biosphere is the regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms. The hydrosphere is all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds. Lastly the atmosphere is the envelope of gases surrounding the earth or another planet, there are 5 different layers Troposphere,Stratosphere, Mesosphere, Thermosphere, and Exosphere. The hydrologic cycle illustrates the changing states of water as it moves through the lithosphere, biosphere, hydrosphere and atmosphere. Thermal energy is transferred as water changes state throughout the cycle.
The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Once the water reaches the ground, one of two processes may occur; 1) some of the water may evaporate back into the atmosphere or 2) the water may penetrate the surface and become groundwater. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.
Water on Earth goes through a cycle known as the hydrological cycle. This cycle has helped to build both snow-capped mountains and dry desert vistas, and has allowed humanity to populate the Earth. By the time it reaches our faucets, however, it may contain harmful elements. During The Flint Michigan Crisis water in Flint, Michigan was changed to the Flint River. Due to insufficient water treatment, over 100,000 residents were potentially exposed to high levels of lead in the drinking water
