Surface Water - Surface water is water on the surface of the planet such as in a stream‚ river‚ lake‚ wetland‚ or ocean. It can be contrasted with groundwater and atmospheric water. - Non-saline surface water is replenished by precipitation and by recruitment from ground-water. It is lost through evaporation‚ seepage into the ground where it becomes ground-water‚ used by plants for transpiration‚ abstracted by mankind for agriculture‚ living‚ industry etc. or discharged to the sea where it becomes

and soil microbes. In some complex forests‚ there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------

water exists in liquid‚ solid‚ and gaseous states water referred to universal solvent ( bipolar molecule enables it to dissolve a wide variety of substances) ice floats ( temperatures drop molecules come together as a solid‚ elections repell (the molecules get less close thus making the ice have less density than water. If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps

Importance of Water All living things need water. The Earth is full of water. Water is the most essential element‚ next to air‚ to our survival. Water makes up more than two thirds of the weight of the human body‚ and without it‚ we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health. Humans and other creatures must drink water to avoid dehydration. Dehydration is defined as a loss or insufficient levels of water and important

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

on the desalination of water. The desalination of water is very important to human and animal life. For centuries humans have used the process of desalination to obtain water safe for consumption.Various methods of desalination have been produced however only some of those methods are widely used today. Although there are numerous methods of desalination all of them involve three liquid streams: the saline feedwater (seawater or brackish water)‚ low-salinity product water‚ and very saline concentrate

Brittany Bolling April‚ 28th 2011 Dr. Woolnough BIO 101 DO6A ABSTRACT: The objective of this study was to observe and understand what occurs in a sample of pond water over the course of six weeks. Over the six weeks there were qualitative and quantitative data found and recorded. The qualitative data recorded entailed: Water color and smell as well as suspended solids ranging from clear‚ opaque‚ and turbid. The quantitative data that was recorded regarded: Temperature‚ pH‚ Alkalinity‚ Hardness

Marukyan Extra Credit MGT 462/November 16‚ 2009 Water Conservation I have attended the presentation about water conservation techniques that each of us can use in our everyday life to ensure the sustainable development of resources and especially water. The presenter on the water conservation was a man who is in charge of the water preservation in Santa Monica. The presentation was very interesting and had great deal of information about proven water conservation tactics. The topics covered included

The water cycle is also known as the hydrologic cycle. The water cycle describes the movement of water on‚ above and below the surface of Earth. Water can change states through the stages of the water cycle. Water can change from a solid to a liquid to water vapor in various places of the water cycle. Water moves from one lake to another‚ just like from an ocean to the atmosphere. Water travels by different processes of evaporation‚ condensation‚ precipitation‚ infiltration‚ runoff and subsurface
