Curious details of Water

Water

WATER

—Water is a chemical substance that is composed of hydrogen and oxygen and is vital for all known forms of life.
—Water on Earth moves continually through a cycle of evaporation or transpiration precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land.
—Clean, fresh drinking water is essential to human and other life forms. Access to safe drinking water has improved steadily and substantially over the last decades in almost every part of the world. There is a clear correlation between access to safe water. However, some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability. A recent report (November 2009) suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%.

PLANETS

—Water vapor has been detected in other planets not only the earth like:
—Water vapor is present in
—Atmosphere of Mercury: 3.4%, and large amounts of water in Mercury's exosphere
—Atmosphere of Venus: 0.002%
—Atmosphere of Mars: 0.03%
—Atmosphere of Jupiter: 0.0004%
—Atmosphere of Saturn – in ices only
—Enceladus (moon of Saturn): 91%
—Water ice is present in
—polar ice caps on Mars
—Moon
—Titan
—Saturn's rings
—Enceladus
—Pluto
—Comets

EARTH

—The collective mass of water found on, under, and over the surface of a planet is called the hydrosphere. Earth's approximate water volume (the total water supply of the world) is 1,360,000,000 km3 (326,000,000 mi3).
—Water covers 71% of the Earth's surface; the oceans contain 97.2% of the Earth's water. The Antarctic ice sheet, which contains 90% of all fresh water on Earth, is visible at the bottom. Condensed atmospheric water can be seen as clouds, contributing to the Earth's albedo.

TYPES OF WATER

—There are many types of water in the world here you will find almost all the types of water:
— Artesian Water
— Distilled Water
— Fluoridated Water
— Mineral Water
— Purified Water

USES OF WATER

—Water resources are useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water.
—97% of water on the Earth is salt water, leaving only 3% as fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is mainly found as groundwater, with only a small fraction present above ground or in the air.
—Fresh water is a renewable resource, yet the world's supply of clean, fresh water is steadily decreasing. Water demand already exceeds supply in many parts of the world and as the world population continues to rise, so too does the water demand. Awareness of the global importance of preserving water for ecosystem services has only recently emerged as, during the 20th century, more than half the world’s wetlands have been lost along with their valuable environmental services. Biodiversity-rich freshwater ecosystems are currently declining faster than marine or land ecosystems. The framework for allocating water resources to water users is known as water rights.

— Spring Wate
— Sterile Water
— Well Water

COLOMBIA'S WATER

—In many regions of Colombia the water is unhealthy like in:
—Choco
—“Costa”
—Tolima
—Villavicencio
—Cali in others…
—It’s unhealthy because the government have not made the special treatment to the water, they don’t make an aqueduct, for that in the regions the people drink water that they pick up in thrash can or the rivers and all this water is polluting.
—The unhealthy water each day is growing because the population is high the fast development and new chemical products in Colombia. The government have not worried about the water to the government it doesn’t matter so the water in many regions is unhealthy.
