Amazing Wonders of Water

Amazing wonders of water, the most important substance on earth, maybe next only to oxygen are here on the pages of this website.

The amazing wonders of water isn’t hidden to humans. Everyone uses water and in fact no one will survive without it for a limited period of time – about a week for most humans. It’s a sought-after substance in the desert and many parts of Africa. In fact, 85% of the world’s population live in the driest parts of the world.

What Is Water?

Water is an inorganic, odorless, transparent, tasteless and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms (in which it acts as a solvent.

Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms.

“Water” is the name of the liquid state of H2O at standard conditions for temperature and pressure.

A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor.

Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (consisting of ice and liquid water suspended in air), and precipitation (0.001%).

Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.

Fishing in salt and fresh water bodies is a major source of food for many parts of the world. Much of the long-distance trade of commodities (such as oil, natural gas, and manufactured products) is transported by boats through seas, rivers, lakes, and canals.

Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes.

Water as found in nature almost always includes various dissolved substances, and special steps are required to obtain chemically pure water.

The Three Common States of Matter of Water

Along with oxidane, water is one of the two official names for the chemical compound H2O; it is also the liquid phase of H2O. The other two common states of matter of water are the solid phase, ice, and the gaseous phase, water vapor or steam.

The addition or removal of heat can cause phase transitions: freezing (water to ice), melting (ice to water), vaporization (water to vapor), condensation (vapor to water), sublimation (ice to vapor) and deposition (vapor to ice).

Water differs from most liquids in that it becomes less dense as it freezes.[ In 1 atm pressure, it reaches its maximum density of 62.43 lb/cu ft at 3.98 °C (39.16 °F). The density of ice is 57.25 lb/cu ft, an expansion of 9%. This expansion can exert enormous pressure, bursting pipes and cracking rocks .

Water can remain in a liquid state at high temperatures in the deep ocean or underground. For example, temperatures exceed 205 °C (401 °F) in Old Faithful, a geyser in Yellowstone National Park. In hydrothermal vents, the temperature can exceed 400 °C (752 °F).

At sea level, the boiling point of water is 100 °C (212 °F). As atmospheric pressure decreases with altitude, the boiling point decreases by 1 °C every 274 meters.

Aquatic plants, algae, and other photosynthetic organisms can live in water up to hundreds of meters deep, because sunlight can reach them. Practically no sunlight reaches the parts of the oceans below 3,300 feet of depth.

Many organic substances (such as fats and oils and alkanes) are hydrophobic, that is, insoluble in water. Many inorganic substances are insoluble too, including most metal oxides, sulfides, and silicates.

A Few More Amazing Wonders of Water

Liquid water can be split into the elements hydrogen and oxygen by passing an electric current through it—a process called electrolysis.

Sound travels long distances in water with little attenuation, (the reduction of the amplitude of a signal, electric current, or other oscillation) especially at low frequencies,a property that is exploited by cetaceans and humans for communication and environment sensing (sonar).

Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is sea water. Water is also present in the atmosphere in solid, liquid, and vapor states. It also exists as groundwater in aquifers.

Water is important in many geological processes. On the surface of the Earth, water is important in both chemical and physical weathering processes.

Dew is small drops of water that are condensed when a high density of water vapor meets a cool surface. Dew usually forms in the morning when the temperature is the lowest, just before sunrise and when the temperature of the earth’s surface starts to increase. Condensed water in the air may also refract sunlight to produce rainbows.

Tides are the cyclic rising and falling of local sea levels caused by the tidal forces of the Moon and the Sun acting on the oceans.

Aquatic Lifeforms

Earth surface 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. Some kinds of animals, such as amphibians, spend portions of their lives in water and portions on land. 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.

Aquatic vertebrates must obtain oxygen to survive, and they do so in various ways. Fish have gills instead of lungs, although some species of fish, such as the lungfish, have both. Marine mammals, such as dolphins, whales, otters, and seals need to surface periodically to breathe air. Some amphibians are able to absorb oxygen through their skin.

Invertebrates exhibit a wide range of modifications to survive in poorly oxygenated waters including breathing tubes (see insect and mollusc siphons) and gills (Carcinus). However, as invertebrate life evolved in an aquatic habitat most have little or no specialization for respiration in water.

Water fit for human consumption is called drinking water or potable water. Water that is not potable may be made potable by filtration or distillation, or by a range of other methods. More than 660 million people do not have access to safe drinking water.

Healthy kidneys can excrete 0.8 to 1 liter of water per hour, but stress such as exercise can reduce this amount.

The single largest (by volume) freshwater resource suitable for drinking is Lake Baikal in Siberia.

The use of water for transportation of materials through rivers and canals as well as the international shipping lanes is an important part of the world economy.

Liquid water is present on Earth, covering 71% of its surface.

The existence of liquid water, and to a lesser extent its gaseous and solid forms, on Earth are vital to the existence of life on Earth as we know it. The Earth is located in the habitable zone of the Solar System; if it were slightly closer to or farther from the Sun (about 5%, or about 8 million kilometers), the conditions which allow the three forms to be present simultaneously would be far less likely to exist.

The surface temperature of Earth has been relatively constant through geologic time despite varying levels of incoming solar radiation (insolation), indicating that a dynamic process governs Earth’s temperature via a combination of greenhouse gases and surface or atmospheric albedo. This proposal is known as the Gaia hypothesis.

The state of water on a planet depends on ambient pressure, which is determined by the planet’s gravity. If a planet is sufficiently massive, the water on it may be solid even at high temperatures, because of the high pressure caused by gravity.

Christians practice water baptism

The amazing wonders of water is part of the world’s religion tenets and beliefs. It is considered a purifier in most religions. Faiths that incorporate ritual washing (ablution) include Christianity, Hinduism, Islam, Judaism, the Rastafari movement, Shinto, Taoism, and Wicca.

There is the same amount of water on Earth as there was when the Earth was formed. The water from your faucet could contain molecules that stayed constant through the world’s history.

A person can live about a month without food, but only about a week without water.

Approximately 400 billion gallons of water are used in the United States per day.

In one year, the average American residence uses over 100,000 gallons (indoors and outside).

Children in the first 6 months of life consume seven times as much water per pound as the average American adult.
