“Water Cycle is a continuous and constant movement of water on, above and below the surface of the earth.” Since water means life, it is better to know how water moves to produce water for human consumption and its essence.
Water cycle circulates around us through three different stages from solids of soil or grounds of the earth, through liquid forms of rivers, lakes and ocean or open seas to gaseous forms or vapors of air and clouds. In this way water are formed in cycle that definitely gives life for humans by giving out fresh water to drink.
Through its cycle, everything on earth is being cared by because water works around the world. It gives importance to new beginnings in life between plants and animals. Living things need water to survive and water cycle does the job. It distribute or give water to plants and animals especially humans that makes it the most vital and important process in sustaining life itself through three different processes of evaporation condensation and precipitation.
Water cycle is important in giving fresh water in all living things. Through evaporation water goes up from bodies of water such as rivers, lakes and oceans and is condensed to form clouds or vapor. After which it will then go back to the ground in the form of rain that gives life to plants and animals that will then be consumed by humans.
Water cycle is also responsible for the climate too! It acts as a force that drives climate and its changes that follows. Temperature is regulated through the process especially during evaporation stage.
It is also called the hydrologic cycle wherein the water in this cycle never leaves the earth atmosphere. It just goes round in circle for this changing life and to support life as it is. It is called hydrologic cycle too because of its continuous repetition or never ending cycle of water from evaporation, condensation to precipitation.
Water compose almost 78% of the earth and around 97% of which is from ocean which are salty and are not good for human consumption that’s why water cycle is there to help the process of providing fresh water in order to provide life.
Water is re circulated through these three processes or stages namely evaporation condensation and precipitation that picture out the whole process of water cycle itself.
Evaporation is the process of which liquid state is turned into gas or vapor during the cycle. It is known or fact, that water bodies such as ocean, rivers and lakes contribute almost 90% of the atmospheric vapor through evaporation leaving the remaining 10% to plants contribution to it. Not mentioning the sublimation process or the transition states that contributes only small amount of it in the atmosphere as vapor through its process where it skip the liquid or the immediate state but instead it turns solid state like ice or snow directly into gas.
Almost all of those evaporated water came from the ocean itself because out of those water bodies around us, the ocean is the biggest of them all. It contributes almost 80% of the water vapor in the atmosphere.
Heat or the energy is the cause of water from surface to evaporate. It evaporates faster at boiling point compared to freezing point where water molecules moves slower. During evaporation process heat is being removed from the environment. It is the most essential element during evaporation process of water cycle.
Opposite of evaporation goes the second phase of water cycle, the condensation or the conversion of atmospheric gas to liquid or water. In this stage, clouds are formed. Condensation is the one responsible in forming clouds which holds the rain for us. Here cool temperature is needed in order for it to happen.
Clouds are formed when water vapor mix up with aerosol or particulate matter in the atmosphere. Here, during condensation process, more and more bumping of the water vapor and the aerosol happen until precipitation then take place or that of saturation. Saturation is the time wherein water in the form of rain comes down or that of tiny ice or snow fall into the ground. Clouds moves in the air as they freely distribute rain water or precipitation all around the globe for us to survive.
The last stage of water cycle now is the precipitation. It is the process wherein heavy clouds are getting heavier and most likely falls down in the form of rain, snow or hail. Here, the aerosol or particulate matter plays an important role. They usually bump each other together with the water vapor until it falls down as rain into the ground.
In this cycle, it simply shows the importance of every stage just to give us fresh water to drink. Human can’t live without water nor can earth do survive without it. Water cycle recycle not only water itself but also some nutrients that human needs too. After which, it will then again be evaporated from the ground to water vapor in cycle.
Water cycle as mentioned earlier is responsible in giving out fresh and usable water for human consumption. As it undergoes those series of processes or stages, salty water is now turned into fresh water and being purified getting rid of those impurities on it along. In short, water cycle helps in cleaning water for human use not only for human alone but for all living things plants and animals as a whole.
It is fact, that out of those percentage of earth’s water holdings, only less than 1% is fresh water that is safe to drink. So since it is the most vital need in human life, we need not only leave it alone to nature or of water cycle itself but rather let us all unite and help Mother Nature produce more fresh water for human use by preserving ecosystem and the earth itself. If we continuously destroy our bodies of water around us with water pollutions, maybe there will come a time that water cycle could never eradicate those harmful elements that will turn out to be hazardous to human life already. Let’s do all save the earth. Preserve and conserve water.
