Water is precious

As the General Assembly of the UN resolved on July 28 of this year, clean drinking water and basic sanitary provision are human rights. Unfortunately, there are more than one billion people all over the world who do not have access to drinking water, while as many as 2.

The water cycle known scientifically as the hydrologic cycle refers to the continuous exchange of water within the hydrospherebetween the atmospheresoil water, surface watergroundwaterand plants. Water moves perpetually through each of these regions in the water cycle consisting of following transfer processes: Precipitation, at a rate of Tt per year over land, has several forms: 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.

Water runoff often collects over watersheds Water is precious into rivers.

A mathematical model used to simulate river or stream flow and calculate water quality parameters is a hydrological transport model. Some water is diverted to irrigation for agriculture.

Rivers and seas offer opportunity for travel and commerce. Through erosionrunoff shapes the environment creating river valleys and deltas which provide rich soil and level ground for the establishment of population centers.

A flood occurs when an area of land, usually low-lying, is covered with water. It is when a river overflows its banks or flood comes from the sea.

A drought is an extended period of months or years when a region notes a deficiency in its water supply. This occurs when a region receives consistently below average precipitation.

Fresh water storage Main article: Water resources The Bay of Fundy at high tide left and low tide right Some runoff water is trapped for periods of time, for example in lakes.

At high altitude, during winter, and in the far north and south, snow collects in ice caps, snow packs and glaciers. Water also infiltrates the ground and goes into aquifers. This groundwater later flows back to the surface in springsor more spectacularly in hot springs and geysers.

Groundwater is also extracted artificially in wells. This water storage is important, since clean, fresh water is essential to human and other land-based life.

In many parts of the world, it is in short supply. Sea water and tides Main articles: Seawater and Tides Sea water contains about 3. The physical properties of sea water differ from fresh water in some important respects. The salinity of water in major seas varies from about 0. 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.

Tides cause changes in the depth of the marine and estuarine water bodies and produce oscillating currents known as tidal streams. The changing tide produced at a given location is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of Earth rotation and the local bathymetry.

The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zoneis an important ecological product of ocean tides.

Water- Precious & Free Gift Of Nature.

From a biological standpoint, water has many distinct properties that are critical for the proliferation of life. It carries out this role by allowing organic compounds to react in ways that ultimately allow replication. 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 within the body.

Metabolism is the sum total of anabolism and catabolism.

In anabolism, water is removed from molecules through energy requiring enzymatic chemical reactions in order to grow larger molecules e. In catabolism, water is used to break bonds in order to generate smaller molecules e.

Without water, these particular metabolic processes could not exist. Water is fundamental to photosynthesis and respiration.Water is a resource that every organism needs to survive.

It is crucial for life’s advancements and our health, which is why it’s important to educate our kids about conservation of water resources.. Through our science, technology, engineering and math (STEM) outreach initiatives, I’ve noticed how much students care about changing the world for the better.

Aug 29,  · Yoder, 71, is deputy director of the county’s water and sewer department; his job is to think about how to defend the county’s fresh drinking water against the effects of climate change.

water is a finite precious resource Although 72% of the Earth’s surface is covered with water, less than 3% of this water is suitable for uses like drinking and irrigation. Water is precious — water is wonderful is a programme about water use and water conservation for use in Year 1 and 2 classes on the Kāpiti Coast.

Introduction Activities are provided so students can investigate water and practise using water safely and wisely. Water is a precious resource and India is already a water distressed country.

Water conservation is a growing concern globally, and particularly for farmers in the USA, where decades of irrigating huge fields has depleted vital resources of fresh surface water and groundwater. Water is a valuable resource, which is why the Fraunhofer Alliance SysWasser is demonstrating how we can extract precious drinking water from air, discover a leak in pipeline systems and even effectively clean sewage water at the IFAT/Entsorga fair (September in Munich, Germany). We recently received the following comment from a reader: "The greatest saver of water for families is to stop trying to recycle. Each time you wash out a can, bottle, or plastic container, you.

Climate change is going to make situation worsts in coming years. But wastage of water is .
