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

Without our atmosphere‚ there would be no life on earth. Two gases make up the bulk of the earth’s atmosphere: nitrogen (78%)‚ and oxygen (21%). Argon‚ carbon dioxide and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth

Know how photochemical smog is produced Hydrocarbons‚ carbon monoxide from vehicle exhausts are irradiated by sunlight in the presence of oxygen gas. The resulting reactions produce a potentially dangerous mixture‚ including other nitrogen oxides‚ ozone‚ and irritating organic compounds‚ as well as carbon dioxide and water vapor. Hydrocarbons + sunlight + O2 + CO + NOx →O3 + NOx + organics + CO2 + H2O Explain why photochemical smog formation varies throughout the day Early morning traffic increases

that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. In the Solar System‚ the atmospheres of Venus‚ Mars‚ and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them‚ Earth’s surface would average about 33 C° (59 F°) colder than

low-lying coastal towns and cities. Ozone Depletion Ozone Layer is formed when ultraviolet radiation (UV) splits a molecule of oxygen (O₂)‚ and the free oxygen atoms (O) combine with other oxygen molecules. Ozone acts as a filter in the upper atmosphere‚ preventing the harmful ultraviolet radiation of the sun from reaching the earth. Carbon compounds such as carbon dioxide (CO₂) and chlorofluorocarbons (CFCs)‚ nitrogen oxides (NO)‚ and methane break up Ozone molecules. Acid Rain Sulfur and

“The Greenhouse Effect” Introduction: The "greenhouse effect" is widely discussed in the media‚ and although its details are complicated‚ its principles are not difficult to understand. Without a greenhouse effect‚ radiation from the Sun (mostly in the form of visible light) would travel to Earth and be changed into heat‚ only to be lost to space. This scenario can be sketched as follows: Sun’s radiation → absorbed by Earth → Re-radiated to space as heat The greenhouse effect is a process where

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

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent. Over the last 100 years‚ the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C‚ or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms‚ floods and raging forest fires
