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

A Glass of Cold water (Cj) Everybody calls me young‚ beautiful‚wonderful Am I? Look at my hair‚ my lips‚ my red rosy cheeks and a pair of blinkering eyes. I remembered somebody says that I look like my mother. But that when she was young. Now I am much lovelier than she is. I’m a mortal venus. Oops! What time is it? I must get ready for the party.

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

drinking water samples from different places using four of the standard drinking water tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan

Water is continuously being recycled in a process called the water cycle. All living things on earth need water to survive. The water cycle has no starting point and no end point. Earth’s water is always in movement and always changing forms‚ it can go from a liquid to a solid to a gas and back to a liquid. The water cycle is how we track movement of water above‚ in and on the earth. The water cycle consists of three major processes‚ condensation‚ evaporation and precipitation. Condensation is the

In this experiment I will find out that in a type of water the Alka-Seltzer will dissolve faster and slower. Alka-Seltzer is one of the world’s best known antacids. Its main function is to absorb excess stomach acid. II. MATERIALS: * Tap Water - Warm Water * Cold Water - Salt Water * Acidic Water -5 cups (250 mL

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted

organisms would not exist without water. Within the human body the majority of biological reactions require water to take place. Although it is possible for human survival without nutrients for up to several weeks‚ without water humans would die in a matter of days. In the human body‚ water makes up 60-70% of adult body weight. At cellular level water makes up between 70-95% of the mass of a cell. The amount of water in the human body is balanced. This balance is between water obtained from liquids consumed
