Jeannie Evers Water Cycle Summary

The article Water Cycle by Jeannie Evers was written on March 26, 2013. The article gives a brief description about the water cycle and how water is exchanged through Earth’s atmosphere, land, and ocean. There is a detailed description of the water cycle processes: evaporation, condensation, and precipitation. Evaporation is the process where liquid changes into a gas from bodies of water driven by the sun and becomes water vapor. Condensation is the process of gas changes into a liquid. Clouds are formed when the water vapor becomes denser. Precipitation is not a process like evaporation and condensation because it is a liquid or solid water that falls to earth and is cycled from the atmosphere to the earth or ocean. The article also mentions the state of water: solid, liquids, and gas. The water cycle influences the earth climate and ecosystems by weather such as humidity and temperature. When water evaporates, it cools the environment by absorbing energy and it warms the environment by releasing energy. The cycle
The impact of the climate change and quality living organism occurs through changes in the water cycle. The articles state different percentages of how much water is on the planet, global precipitation occurs, and evaporation. Evaporation will lose fresh water and precipitation will gain it which determines the surface salinity of the ocean. Temperature and salinity control the density of the ocean water. NASA has been researching the water cycle and measuring evaporation, condensation, and precipitation, ground water flow, runoff, and ice accumulation by a myriad. They will be monitoring water in the environment by using six aqua instruments. Since water vapor is the known as the earth greenhouse gas they will be focusing on the uncertainties in estimate of future global warming, because it important to understand the earth
