Answer: Water is the most important liquid for all living forms. It is not only necessary for our life processes but is also required for the functioning of our planet. Water is available in 3 states on the Earth- solid, liquid, and gaseous. Solid-state includes glaciers, snow caps, ice sheets, and polar ice reserves. The liquid state includes rivers, seas, lakes, ponds, streams, oceans, and geysers. The gaseous state includes water vapor found in the atmosphere. No matter which state it is in, the composition of Water remains the same throughout. It is a powerful compound that nurtures all the life present on Earth. Plants require water for photosynthesis and respiration. Humans require water for many different life processes like circulation, digestion, respiration, and excretion, without Water, life would be impossible on Earth. As it is such an important compound, we must make sure that we conserve it so that it won’t get exhausted soon.
