Water Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds.

The water in you Water serves a number of essential functions to keep us all going: A vital nutrient to the life of every cell, acts first as a building material. It regulates our internal body temperature by sweating and respiration; The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream; It assists in flushing waste mainly through urination; acts as a shock absorber for brain, spinal cord, and fetus; forms saliva

Why the earth called a water planet? Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms.

water a colourless, odourless liquid that is the most abundant component of any organism (over 60% by weight in humans). Life almost certainly originated in water and it provides the medium for biological reactions to take place.

- The world’s water exists naturally in different forms and locations: in the air, on the surface, below the ground, and in the oceans. Freshwater accounts for only 2.5% of the Earth’s water, and most of it is frozen in glaciers and ice caps.

Water resources Surface water is water in a river, lake or fresh water wetland. Surface water is naturally replenished by precipitation and naturally lost through discharge to the oceans, evaporation, evapotranspiration and groundwater recharge.

Water, Water, Everywhere Water is everywhere on Earth. About seventy percent of the surface of the Earth is covered by water. If you were an alien visiting the planet, you would see a giant blue sphere from space (especially on the Pacific Ocean side). Not only is water everywhere, but all life depends on water. The tiniest bacteria and the largest dinosaurs have all needed water. The hydrosphere is the world of water that surrounds all of us. Because water is so important, it makes up an entire section of the earth sciences.

The Water Cycle: Precipitation, Condensation, and Evaporation Where is Water? The water cycle, also known as the hydrologic cycle, is the process by which water moves from place to place above, on, and below the Earth's surface. This is the process by which water moves around the Earth to different places.

- Water is a compound composed of the two elements hydrogen and oxygen. This amazing substance can exist near the earth’s surface in all three physical forms: as a liquid, vapor or gas and as a solid. The humidity in the air is a measure of the amount of water vapor suspended within it.

Water Is Magicâ¦ Water Is Magic…. Water is the essence of life on Earth and dominates the chemical composition of all organisms. “The ubiquity of water in biota as the fulcrum of biochemical metabolism rests on its unique physical and chemical properties,” says Robert G. Wetzel, scientist and author of the textbook Limnology (2001). Water is unique. And mysterious.

water cycle The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three places, and in many forms—as lakes and rivers, glaciers and ice sheets, oceans and seas, underground aquifers, and vapor in the air and clouds.

Water resources Water resources are sources of water that are potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.

Water: A Never-ending Story Background. Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology. In the water cycle, the sun heats the Earth's surface water, causing that surface water to evaporate (gas).

It's Just a Phase: Water as a Solid, Liquid, and Gas Water is an essential part of the earth system. Water is special not only because it covers over 70% of the earth's surface, but also because it is the only known substance that can exist in gaseous, liquid, and solid phases within the relatively narrow range of temperatures and pressures found on earth.

Dry water Dry water. Dry water. Dry water, an unusual form of powdered liquid, is a water-air emulsion in which tiny water droplets, each the size of a grain of sand, are surrounded by a sandy silica coating. Dry water actually consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid.

How Water Works Human Water Consumption. Our bodies are about 60 percent water [source: Mayo Clinic ]. Water regulates our body temperature, moves nutrients through our cells, keeps our mucous membranes moist and flushes waste from our bodies. Our lungs are 90 percent water, our brains are 70 percent water and our blood is more than 80 percent water. Simply put, we can't function without it.

It includes all liquid and frozen surface waters, groundwater held in soil and rock, and atmospheric water vapour. Water is the most abundant substance at the surface of Earth. About 1.4 billion cubic kilometres (326 million cubic miles) of water in liquid and frozen form make up the oceans, lakes, streams, glaciers, and groundwaters found there.
