Why Sea Water is Salty The “salt” in sea water‚ and some lakes that have no water outlet such as the Great Salt Lake and the Dead Sea‚ comes from ions of dissolved minerals‚ mainly chloride and sodium which make up about 90% of salt ions in sea water. There are three main ways that dissolved minerals enter the ocean: The water cycle‚ underwater geysers know as Hydrothermal Vents‚ and underwater volcanos. During the water cycle‚ water is evaporated from bodies of water by the heat of the

Overview of water resources in Pakistan The total land area of Pakistan is approximately 310‚322 square miles or 88 million hectares of land‚ of which approximately 20 million heaters are used for agriculture purposes. The river system of Indus and its tributaries provides Pakistan some of the most fertile land in the Indian subcontinent. Under the Indus Water Basin Treaty of 1960 three eastern rivers namely: Sutlej‚ Beas and Ravi were allocated to India for its exclusive use. The Treaty gives

importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water as a

Air and water pollution affect the biotic and abiotic environment on a global scale. All pollutants affect individuals in different ways‚ but mainly affect those with asthma or underlying respiratory conditions. Transportation and energy consumption are the biggest contributors to pollution and global warming. With world population on the rise‚ carbon dioxide in the atmosphere is also climbing a steep hill. CO2‚ a primary air pollutant‚ is the most major concern amongst environmental scientists‚

Water is essential to all living things‚ be it plants for photosynthesis or animal or bodily functions. The human body requires water to cleanse and maintain the body. When we sustain a good supply of it‚ we are hydrated. The term for when we are lacking in water is dehydration. Staying hydrated and knowing the signs of dehydration are simple yet important tasks. The basic way of staying hydrated is drinking water. Doctors suggest a minimum of six to eight ounce glasses per day. However‚ those

diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at the same time. However‚ more water leaves a dilute
