effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should prevent this from happening‚ but the ozone layer has deteriorated quite considerably due to the world’s continuously increasing burning of fossil fuels and the vast overuse of fossil fuel-powered vehicles. As a result‚ the earth’s average temperature has

Environmental effects of Air Pollution and the Urban Area Air pollution has been and is a growing environmental problem that is closely related to the growth of urban settlements. While the cities and towns of the world grow larger they emit more and more toxic emissions are put out into the air. The purpose of this paper is to discuss the issues that surround air pollution such as the long term impacts of air pollution‚ the short term impacts of air pollution‚ the long term outlook of air pollution

AIR POLLUTION AND CLIMATIC CHANGES Introduction: Air pollution is actually the addition of any harmful substances to the atmosphere‚ which causes the damaging of the environment‚ human health and the quality of life. Air pollution has been a serious problem throughout the history. This can have series effect on the health of human beings. Every day‚ the average person inhales about 20‚000 liters of air. Every time when we breathe in we inhale dangerous substances. These dangerous substances can

1. An atmosphere (New Latin atmosphaera‚ created in the 17th century from Greek ?tµ?? [atmos] "vapor"[1] and sfa??a [sphaira] "sphere"[2]) is a layer of gases surrounding a planet or other material body of sufficient mass[3] that is held in place by the gravity of the body. An atmosphere is more likely to be retained if the gravity is high and the atmosphere’s temperature is low. Earth’s atmosphere‚ which contains oxygen used by most organisms for respiration and carbon dioxide used by plants‚ algae

Figure 1.1 (Wikimedia‚ 2012) Our Atmosphere The atmosphere is best described as a series of concentric circles enveloping our earth. Each circle is layer with a unique chemical composition‚ temperature range and function. Chemical Composition of the Atmosphere The current molecular composition of Earth’s atmosphere is diatomic nitrogen (N2)‚ 78.08 percent; diatomic oxygen

____________________________________________ Period _________ Date _________________ Earth’s Dimensions Unit: Layers of the Atmosphere & Earth’s Interior INTRODUCTION: The Earth’s atmosphere is divided into 4 layers. There is a boundary where each layer ends and a new one begins and a name is given to this boundary – a pause. Distinct temperature differences are found within each layer. For example‚ at the stratopause‚ the temperature stops increasing with altitude. The overlying mesosphere

with chemicals. Pollution of the atmosphere and the air around us is air pollution‚ and this is becoming more "popular" everyday. There are several main types of air pollution that include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. The types are extremely harmful to the environment and could result in serious damage. There are many causes of air pollution and there are many to blame. The first type of air pollution is smog. The word smog came from a newspaper article almost

However‚ by December 2011 that number increased to over 246.3 trillion automobiles. With such a high incline‚ how do automobiles affect our environment and the ozone layer? Majority of the pollution throughout our nation is caused by automobiles. The ozone layer is there to protect life from the ultraviolent rays from the sun. These layers become depleted due to high concentrations of chlorine or bromine atoms and include chlorofluorocarbons‚ or CFC’s‚ halons‚ methyl bromide‚ carbon tetrachloride
