Water Project
From a biological standpoint, water has many distinct properties that are critical for the proliferation of life that set it apart from other substances. All known forms of life depend on water. Water is vital both as a solvent in which many of the body's solutes dissolve and as an essential part of many metabolic processes. In anabolism, water is removed from molecules in order to grow larger molecules. In catabolism, water is used to break bonds in order to generate smaller molecules. Water is also central to photosynthesis and respiration.
Earth's waters are filled with life. The earliest life forms appeared in water; nearly all fish live exclusively in water, and there are many types of marine mammals, such as dolphins and whales that also live in the water. Plants such as kelp and algae grow in the water and are the basis for some underwater ecosystems. Plankton is generally the foundation of the ocean food chain.
Water politics is politics affected by water and water resources. For this reason, water is a strategic resource in the globe and an important element in many political conflicts. It causes health impacts and damage to biodiversity. A 2006 United Nations report stated that "there is enough water for everyone", but that access to it is hampered by mismanagement and corruption.
Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity, Hinduism, Rastafari movement, Islam, Shinto, Taoism, and Judaism.
The Ancient Greek philosopher Empedocles held that water is one of the four classical elements along with fire, earth and air, and was regarded as the ylem, or basic substance of the universe. Water was considered cold and moist. In the theory of the four bodily humors, water was associated with phlegm. The classical element of Water was also one of the five elements in traditional Chinese philosophy, along with earth, fire, wood, andmetal.
Water is used in literature as a symbol of purification.
Water is the chemical substance with chemical formula H2O: one molecule of water has twohydrogen atoms covalently bonded to a singleoxygen atom.
Water appears in nature in all three common states of matter and may take many different forms on Earth: water vapor and clouds in the sky; seawaterand icebergs in the polar oceans; glaciers and riversin the mountains; and the liquid in aquifers in the ground.
The major chemical and physical properties of water are:
§ Water is a tasteless, odorless liquid at standard temperature and pressure. The color of water and ice is, intrinsically, a very slight blue hue, although water appears colorless in small quantities. Ice also appears colorless, and water vapor is essentially invisible as a gas.
§ Water is transparent, and thus aquatic plants can live within the water because sunlight can reach them. Only strong UV light is slightly absorbed.
Water on Earth
Hydrology is the study of the movement, distribution, and quality of water throughout the Earth. The study of the distribution of water is hydrography. The study of the distribution and movement of groundwater is hydrogeology, of glaciers is glaciology, of inland waters is limnology and distribution of oceans isoceanography. Ecological processes with hydrology are in focus of ecohydrology.
The collective mass of water found on, under, and over the surface of a planet is called thehydrosphere. Earth's approximate water volume is 1,360,000,000 km3.
Effects on Human Civilization
Water fit for human consumption is called drinking water or potable water. Water that is not potable can be made potable by filtration or distillation (heating it until it becomes water vapor, and then capturing the vapor without any of the impurities it leaves behind), or by other methods (chemical or heat treatment that kills bacteria). Sometimes the term safe water is applied to potable water of a lower quality threshold (i.e., it is used effectively for nutrition in humans that have weak access to water cleaning processes, and does more good than harm). Water that is not fit for drinking but is not harmful for humans when used for swimming or bathing is called by various names other than potable or drinking water, and is sometimes called safe water, or "safe for bathing". Chlorine is a skin and mucous membrane irritant that is used to make water safe for bathing or drinking. Its use is highly technical and is usually monitored by government regulations.
Song for the Water project.
Bright Water
Water clear, water bright,
Is a friend to clean;
Water clear, water bright,
Serves us to have a dream.
Take care of it,
Or you will be mean,
Water is bright,
Take care of it.
Water clear, water bright,
Is a friend that clean;
Water clear, water bright,
It cleans al that you need.
Little raindrops, lightly falling,
Take care of it;
And rains early in the morning,
Began to care it.
Water clear, water bright,
Is a wet thing;
Water clear, water bright,
Water is all you need.
In the ocean is blue,
Need to care it;
The sea is a clue,
Care all of it.
Water clear, water bright,
Is a friend of living things;
Water clear, water bright,
Care it for things.
