Features of Water
Water makes up more than two-thirds (71%) of the Earth's surface. It continually moves and shifts, existing in its different forms in oceans, lakes, clouds, the air, vegetation, glaciers, and snow, not mention what is underground. Water has some unique characteristics. For example, while substances can take on the various forms of solid, liquid, or gas, water is unusual in that, unlike other substances, it doesn't require extreme temperatures to do so, rather, it changes under conditions that life can tolerate. In addition, when solids of a substance form, the atoms typically come closer together to make the substance more dense. Water molecules, on the other hand, form rings when they freeze, making the substance less dense. Thus, while most solids sink in water, solid water (ice) is able to stay afloat. Water's unique features are what allow it to be everywhere and to impact everything, including out own bodies and health. These properties are also what give it deeper symbolic meaning. For instance, water is never lost; it just changes form. It "adapts" to its environment in ways that enhance the lives of all. For instance, under heat, it elevates and gives rise to clouds that provide a divine vision that has moved people for millennia. And when water freezes into buoyant ice, it provides a kind of insulation for the fish and plant life that remain below. Stay tuned for Part 3 Water's importance to Health.
