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

Factories contribute to water and land pollution by chemical spills and discharge of toxic waste. These two factors are the main causes of environmental problems in Malaysia. Consequently‚ it had brought ill effects such as global warming‚ acid rain and ozone depletion. In recent decades‚ global warming‚ which is linked to the emission of greenhouse gases‚ affect the planet in variety ways. Global warming refers to gradual climate changes in the form of increased temperature. Due to global warming‚ Malaysia

show you more about ozone depletion and how it relates to indoor air pollution. According to our text ozone "is a naturally produced‚ essential component in the stratosphere‚ which encircles our planet some 10 to 45 km (6 to 28 mi) above the surface." (Berg‚ Hager‚ & Hassenzahl. 2011). Ozone in the stratosphere is a good thing‚ when in this layer it absorbs much of the suns ultraviolet rays and protects us from harm. In the troposphere however‚ it is a different story. Ozone there is a combination

Global warming itself is a term used to describe the change of the temperature of the earth that can finally change the climate on earth. We have known it for a long time that our earth is becoming hotter year by year. There are a lot of things that can cause global warming. Air pollution is one of the causes that can
