Oxygen is one of the most important and abundant elements on Earth. About 46 percent of the Earth’s crust is oxygen. It is colorless and odorless and makes up about 20.95 percent of the atmosphere by volume. Oxygen exists in water as part of water molecule‚ in the atmosphere as a gas‚ in the Earth’s crust and in an enormous variety of rocks and minerals. It can also be released from the plants through photosynthesis. Moreover it is very essential for life and is part of almost every biological molecule

The atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen and ozone. In addition‚ there is some amount of water vapour. The atmosphere exists in layer called troposphere‚stratosphere‚ionoshhere and exosphere in that order from the surface of earth. The atmosphere is not static and is moving constantly with respect

through the action of sunlight on previously emitted reactive materials. For example‚ ozone‚ a dangerous pollutant in smog‚ is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. On the other hand‚ the discovery in the 1980s that air pollutants such as fluorocarbons are causing a loss of ozone from the earth ’s protective ozone layer has caused the phasing out of these materials. Current information about the

What is water purification? Water purification generally means freeing water from any kind of impurity it contains‚ such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some

infrastructural development progressing at a rapid rate‚ some harmful chemicals that are produced from science and technological equipment are disposed in the environment. Due to the subsequent increase in the amount of these chemicals in the atmosphere‚ the Ozone layer that prevents harmful particles from entering into the earth atmosphere gets depleted causing those harmful particles to enter into the earth atmosphere. Due to this‚ the earth’s environment is disturbed‚ which‚ in time‚ results in very high

oxide produced by big industries and car emissions. When there is an overabundance of pollution in the air the sun’s rays get trapped on earth because of something called the Ozone layer. The Ozone layer is the part of the Earth’s atmosphere which contains relatively high concentrations of Ozone (O3). This causes the ozone to be

Premium Air pollution
two settings are water vapor in the air‚ the aerosols‚ ozone depletion. The water vapor in the air can affect temperatures by absorbing heat energy given off the Earth (Lutgens et al‚ 2011). Another factor that might affect temperatures is aerosols which can absorbs or reflect in coming radiation (Lutgens et al‚ 2011). Ozone depletion is the final factor that might affect temperatures because the ozone filters out UV radiation from the sun‚ ozone depletion can cause changes in temperature. Lutgens
