The Hydrological Cycle

 Air pollution that causes pollution in water may be determine by the hydrological cycle which moves and carries the water.

The Hydrologic cycle is a model that describes the storage and movement of water between the, biosphere, atmosphere, and the hydrosphere(Hubbert 2010). This water evaporates from moist surfaces, falls as rain or snow, passes through living organisms, and returns to the ocean (Cunningham, Cunningham 2010).

The Hydrologic cycle begins with evaporation from the surface of the ocean. According to Bramer, moisture is than transported by the winds around the globe until it returns to the surface as precipitation. Once the water reaches the ground, it may evaporate back again, or penetrate the surface and become ground water states the article of the Hydrological Cycle. The ground water may seep into the river, lake, and ocean, or it may be released back into the atmosphere through transpiration according to the article "A Summary of The Hydrological Cycle." The remains of the water on the Earth's surface is runoffs, which goes back to lakes and rivers that carries it to the ocean (Bramer 2010). The Hydrological Cycle than begins again.
