Fresh Water Resources Water - Basic Knowledge Made up of 2 hydrogen and one oxygen We can live without food for 50-60 days‚ but we can only live without water for 1-2 days (3 at most) Water resources are scarce Life without water is why we don’t live on mars Hydrologic cycle Describes the continuous movement and distribution of water on‚ above‚ and below earth’s surface By changing its state‚ water moves among great global reservoirs 3 stages: gas‚ liquid‚ solid (ice) When solid‚ it expands

Water is a chemical compound with the chemical formula H 2O. A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state‚ steam (water vapor). Water covers 71% of the Earth’s surface‚ and is vital for all known forms of life.[2] On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚

WATER LOGGING AND SALINITY Naheed Ghazanfar Izhar & Associates Consulting 5.1 CLASSIFICATION OF WATER LOGGED AND SALINE AREAS BY DEGREE The existing irrigation system in Khyber Pakhtunkhwa was developed in late 1800s over a century ago. This system was designed for the farming at that time which was much lower than the cropping intensities of today. This system had limited provision for drainage‚ resulting in a rise in groundwater and the occurrence of salinity. |Table

specific heat is one of five properties of water that is important to life. Specific heat is defined as the heat necessary to raise one gram of water by one degree Celsius. Because water’s temperature does not change dramatically when absorbing or losing heat‚ water can absorb or release exceeding amounts of heat (by breaking and forming hydrogen bonds) without affecting living organisms in the water and at the same time helping terrestrial organisms outside the water live easier. For example‚ coastal areas

Tap Water should be the Water of Choice Scientists have warned for years that when bottles are stored in warm and hot temperatures‚ the plastic been showed to leach chemicals into the water. There are increasing effects of polyethylene terephthalate bottles on our environment. Even the price of bottle water is increasingly outrageous. With the economy the way it is‚ why spend the money on bottle water. The EPA conducted studies on chemicals found in bottled water. Even though the studies found

Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

The Water Cycle Intro How come we never run out of water? After millions of years you’d think that our water supply would be all used up right! It’s not though‚ because of one special process‚ the hydrologic cycle‚ more commonly known as "the water cycle." Main Points This water cycle recycles the Earth’s water supply. In other words‚ the water keeps getting reused over and over. Just think‚ the next glass of water you drink could have been part of a dinosaur’s bath‚ one

Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually

Water and Soil Protection Soil Contamination: Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo (a) pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals.
