Check out this article for the water cycle: This is the process where water is changed from liquid form to water vapor. Evaporation requires a significant amount of energy. Importance of Water Cycle. So far, we have discussed the water cycle technically. But what you may not know is why this process is so essential. Evaporation. But it is necessary to discuss its importance in everyday life. Water is one of the key ingredients to life on Earth. The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. All the humans, animals, and plants around the earth have access to fresh water – that’s why we are alive. The total amount of water remains essentially constant. About 75 percent of our planet is covered by water or ice. For example, we humans get the water from rivers, ground, or direct precipitation. This is a reversible cycle, which means every stage in the cycle keeps repeating itself. Water is very important for all living beings. Water cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. The water cycle process encompasses 6 stages. Now write a paragraph description of each––where it comes from, what it can be used for, how humans access it––and you have your essay. The water cycle is the endless process that connects all of that water. Water cycle keeps providing us with freshwater continuously. Processes of the Water Cycle. These are evaporation, transpiration, condensation, precipitation, interception, and infiltration, which is the focus of this article.. 1. You've likely heard of the hydrologic (water) cycle before and know that it describes how Earth's water journeys from the land to the sky, and back again. Add to that man's ability to reclaim water, and you have seven main sources of water: The ocean, lakes and streams, groundwater, snow and ice, water vapor (in the air), grey water, and reclaimed water. During this process, water changes its state from one phase to another, but the total number of water particles remains the same. It joins the Earth’s oceans, land, and atmosphere. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. Of the world's total water supply, 97% is salt water found in our oceans.That means that less than 3% of available water is freshwater and acceptable for our use. Learn more about Earth's water cycle on the Precipitation Education website. This cycle is also called the H2O cycle or the hydrologic cycle. Water cycle is a simple to understand process. If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life.
