Water is an essential part of human life. It is referred to as the hydrophilic part of the earth crust, and it constitutes 70 percent of the earth. There are various forms by which water can be conserved; the rainwater, tap water, borehole water, water bodies such as rivers, seas, oceans, and streams. Good water is said to be odorless, tasteless, and colorless. The cycle of water is a continual one as water is being evaporated from the water bodies to the atmosphere, the water in the vegetation also goes up in the form of transportation, then after condensation, there is precipitation whereby the waterfalls to the earth surface in the form of rain, and lastly, all the inland waters find their ways to the sea.
Evaporation is a process whereby water is being turned from its liquid state to gaseous state in the process of heat energy application. Plants intake their water from the root through the stem, and when the water gets to their leaves, it goes up to the atmosphere through the stomata, opening in the outer part of the skin. When evaporation and transpiration occur simultaneously, then it is called evapotranspiration.
