The phenomenon known as the water cycle is one that causes water to transform its states at different times to remain as one of the most important elements of the planet. The water cycle is a very complex cycle that happens from the interaction of chemical reactions with biological and geographical reactions. It is important to note that without the water cycle humans would not be able to access this natural element as it would become an exhaustible resource being in one state and not recreating again and again.
The water cycle is a continuous cycle that does not have an easily determined beginning or end because it is in constant generation. In addition, the water cycle is complex because although it is relatively linear, each of its stages can lead to different spaces and areas that are not univocal. To understand how this cycle occurs, it is important to begin by pointing out that water, one of the most natural elements found on the planet, is present in three possible different states: solid state, liquid state and gaseous state. Each of these states is represented by ice or snow, flowing water or gas vapor, respectively.
One of the first steps from which the water cycle develops is when clouds or water vapor, ie water in the gaseous state, are present in the atmosphere. This water vapor can be generated by the evaporation of the oceans and other aqueous spaces. Thus, we speak of evaporation and condensation when that evaporated water condenses as clouds.
As these cloud formations or gases are normally found at very low temperatures, they become heavy and dense clouds that begin to generate precipitations in the form of water or snow (solid and liquid states respectively). This period is then known as precipitation. Both the water and the snow infiltrate the earth generating underground water stores. Another very important amount of water flows into springs, rivers and eventually seas and oceans, returning to the place from where the cycle begins and feeding all the different spaces in which there is water.
