Carbon Dioxide Greenhouse Effect
1,080 wordsWhile some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls an...

Released Into The Atmosphere Greenhouse Gases
958 wordsGlobal warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. (Melissa Phillips). This results in an increased emission of greenhouse gases. (Caroline Quatman). Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. (Brent C. Willhoite) Climate changes occu...

Countries In The World Carbon Monoxide
1,085 wordsSection A: Declining Air Quality The declining air quality can be held responsible for many things such as city smog and the greenhouse effect. Such problems are very definite in America since they are one of the top airpollutantcreating countries in the world. The original list of air pollutants created by US industries was made up of arsenic, asbestos, benzene, beryllium, coke oven emissions, mercury, radionuclides (radioactive isotopes), and vinyl chloride. In the 1990 s this list was expande...

Catalytic Converter Carbon Monoxide
705 wordsIntroduction There are millions of cars on the road in the United States, and each one is a source of air pollution. Especially in large cities, the amount of pollution cars produce everyday is a lot. To solve those problems, many laws have been enacted restricting the amount of pollution that cars can produce. To make their cars as pollution-free as possible, automakers have made many refinements to car engines and fuel systems and have developed the catalytic converter. The catalytic converter...

Nitrous Oxide Liquid Nitrogen
551 wordsNitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776. Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes have been artificially prepared. Nitrogen melts at - 210. 01 C (- 3...

Clean Air Act Nitrogen Oxide
721 wordsUrban Environmental Science A human being breathes 16 times a minute, 960 times an hour, almost 8. 5 million times a year. With each breath, he or she inhales hundreds of airborne substances. The nature of these substances is partially formed by the human activity. For those who live in cities, many of those substances are pollutants that increases the risk of respiratory problems and cancer. Smog reduces lung capacity and decreases the body's ability to fight infection. Soot causes bronchitis, ...

Carbon Dioxide Nitrogen Oxide
1,100 wordsThe greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. ? The glass? lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO 2), and methane which comes mainly f...

Degrees Celsius Mental Disorders
1,099 wordsIn 1817, an aging Swedish chemist was pouring over his work on a late afternoon in Stockholm, Sweden. He was analyzing a strange ore named Petalite that had been procured from an island off the coast of Sweden called Ut&our; . The ore Petalite (which is now recognized to be Li Al (Si 2 O 5) 2) had been discovered by a Brazilian scientist, Jos&execute; Bonus´ cio de Andrada e Silva towards the end of the 18 th century on a visit to Sweden.

Burning Of Fossil Fuels Greenhouse Gases
888 wordsMany people disagree on the issue concerning global warming. Some believe that human activities, various forms of polluting, are the main cause of global warming. Others think that not only have humans not affected the planet by any significant amount, but that not much global warming has even occurred. Many scientists think that pollution is the cause of global warming and the greenhouse effect. There is a lot of evidence to support this theory. In the United States alone, almost 15, 000 pounds...

Earth Surface Stop Global Warming
980 wordsIn the last century, the earth? s surface temperature has increased 0. 45 - 0. 60 degrees celsius. Although some scientists believe global warming is not a problem, many scientists believe that global warming is a serious problem, and can not be ignored. Global warming, as the term implies, is the increasing temperature of earth. A factor that is believed to play a part in this is the greenhouse effect, which is the effect in which greenhouse gasses, such as carbon dioxide allow incoming solar r...

Surface Of The Earth Nitrous Oxide
613 wordsGlobal Global Warming Introduction: Global warming is a term that describes the green house effect-that is rise in temperature of the earth. The earths climate is predicted to change because activities are altering the chemical composition of through the building up of green house gases-primarily CO 2, CH 3, N 2 O and chlorofluorocarbon. These green house gases trap energy from the sun and heat would not escape back in to space. Thus, they warm our world. But problem is arising because the atmos...

Nitrous Oxide Carbon Dioxide
555 wordsThe Greenhouse Effect Earth is the only planet that we know of that has the right conditions to support life. Because of it s perfect distance from the sun, Earth has an average temperature of 60. F, making it an ideal place for many types of life to thrive in. However, the temperature would not be so ideal if we did not have an atmosphere with certain gasses in it. Without the help of gasses such as carbon dioxide, water vapor, and others, the Earths climate would not be suitable for life. Ener...

Peptide Bonds Test Tube
606 wordsThis lab used many test to determine which functional groups were present in certain substance. The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reduce the Caprice ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when at low levels. In both the onion juice and glucose solution the reducing sugar levels were very high, because the test came back dark oran...

Uv Radiation Ozone Depletion
993 wordsOur Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35 km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that ...

Acid Rain Sulfur Dioxide
609 wordsAcid RainA Contemporary World Problem Acid rain is one of the most dangerous and widespread forms of pollution. Sometimes called the unseen plague, acid rain can go undetected in an area for years. Technically, acid rain is rain that has a larger amount of acid in it than what is normal. The acidity of rain in parts of Europe and North America has dramatically increased over the past few decades. It is now common in many places for rain to be ten to seventy times more acid than unpolluted rain. ...
