Ground Water and Drinking Water: An Expert Guide for Kids


There is a reason why parents tell kids to drink more water. Water is essential to human beings in order to survive. Believe it or not, water makes up 75% of the total weight of the human body. It aslo performs many important roles to keep the body functioning. It dissolves and replenishes nutrients and essential organic matter, and transports them to different parts of the body. In addition, it keeps the body clean by flushing out waste materials. In fact, water is more important to human survival than food. A person who is lost in the wilderness can survive for 8 weeks without food if he or she drinks enough water. Nevertheless, he or she can only live for 3 to 5 days without drinking any water.

Water is as old as the Earth, and it has been around for millions of years. The water that is used by human beings and animals today existed during the times when dinosaurs roamed the Earth. How is that possible? Well, natural water goes through a process called water cycle. In this process, the water that is present on the surface of the Earth will evaporate when it is heated by the sun, and it will rise to the sky to form clouds. Since the temperature in the sky is cold, the clouds will condense and fall as rain. The rain will either fill up rivers, lakes, wetlands, and oceans, or seep into the earth to become ground water. Human beings also build reservoirs and other structures to collect water. Fresh water in some places contains nasty bacteria that can cause disease, and it has to be purified before it is consumed. Bottled water and other types of water that are consumed today have been purified, and they are all safe for drinking.
