PARAGRAPH ON WATER OUR BASIC NEED
Answers
Answer:
Water is the basic need of every life form on Earth. It is Water that helps us to lead a comfortable life on this planet. Our bodies are made up of 70% water, which is why Water is such an important compound for us. We use Water for so many purposes.
Water is recognized as a universal solvent. This characteristic of Water that makes it so important for life on Earth to flourish. It has two molecules of Hydrogen joined by double covalent bonds with a single molecule of Oxygen. The covalent bonds give Water its solubilizing properties. It can dissolve a large number of solids, liquids, and gases within itself. Our bodies require 70% of Water to function properly. Most of this Water is used for transporting nutrients to different parts of our bodies and bringing back toxins from them that would be ultimately excreted out.
Water is found in abundance on the Earth but, only 1 percent of it can be used for drinking purposes. This 1 % is known as potable water and is found in freshwater resources like glaciers, streams, lakes, rivers, and ponds. With time, the share of clean freshwater has been deteriorating. Most of the freshwater that we use comes from rivers and underground reservoirs. Overexploitation of these resources has led to a decrease in water levels in these bodies.
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.
