The Study of the Ozone Layer
OZONE LAYER The ozone is made from oxygen, but for billions of years there was no actuall oxygen in the earth's atmosphere. The earth's primitive atmosphere is said by scientist that it was composed of water vapor,carbon dioxide,sulfur dioxide, nitrogen,and other gases released by volcanic and other activitys from the planets hot interior. Because there was no oxygen, there was no ozone, and all the sun's ultraviolet radiation reached the earth's surface. THis ultraviolet radiation had enough ...

Ozone
Ozone, pronounced OH Zohn, is a form of oxygen that is present in the earth's atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Ozone is used commercially in water purification process and as a bleaching agent. Ordinary oxygen molecules have two oxygen atoms, ozone has three. Ozone is produced naturally through photochemical and electric discharge reactions. Photoch ... Ozone has a molecular weight of 47,998, pure ozone is a pale blue gas. ... This ozone layer in the upper atmosphere shields the earth from 95 to 99 per cent of the sun's ultraviolet rays. ... Exposure to certain concentrations causes headaches, burning eyes, and irritation of the respiratory tract in many individuals In the mid 1970's, some scientist expressed concern that chemical compounds called chlorofluorocarbons ( cfc's ) were breaking down the protective layer of ozone. ...

The Results of Air Pollution
Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both ... The hole in the ozone layer over Antarctica has grown to its greatest size yet, the US space agency says. Nasa says this year's hole in the ozone layer - an annual event around September and October - measures 11 million square miles. ... Scientists who have been studying the ozone layer since the early 1970s were shocked by the hole's size. Dr Michael Kurylo, manager of Nasa's Upper Atmosphere Research Program, said: "These observations reinforce concerns about the weakness of Earth's ozone layer." The ozone layer protects our planet from harmful ultraviolet radiation and ... Wordcount: 842 Pages: 3
Atmospheric Crisis Causing Global Warming
We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year. These chemicals are brewing a disastrous stew, resulting in an atmosphere crisis. The greatest consequences of the atmosphere crisis may be the greenhouse effect( global warming) and the ozone deletion. If humankind wants to survive well into the next millennium, than we must stop this horrid des ... And, scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the sun. Once the ozone layer is completely destroyed, all life on Earth will cease to exist, killed by the deadly radiation. ... Currently, about 80% of the ozone layer disappeared from an area centered on Antarctica that was nearly the size of North America. ... Every day, every single human being, contributes in some way, to the destruction of the ozone layer, from using deodorant sprays, to throwing away perfectly recyclable material...

rain forest
RAIN FOREST JOURNAL ESSAY Every second, one acre of all the Earth"s rain forests is destroyed. Already, half of all the rain forests have been destroyed. This is unacceptable and it must be stopped. We all must help with all our efforts to save the rain forests. If we keep on cutting down the rain forests at this pace, there will be no rain forests left in fifty years! A rain forest is a forest that gets a lot of rain and holds thousands of plants and animals . many which are not yet ... All trees take in carbon dioxide, which can be harmful to the ozone layer. Because of the pollution from the cars, the ozone layer is getting holes in it. Because of the eroding of the ozone layer, there is not as much protection from the sun, which means in certain spots, the sun may be shining directly to the surface, because the ozone layer is not there anymore. If all the trees are cut down in the rain forests, there will be nothing to take in the harmful carbon dioxide and the ozone layer will be no more. ... Wordcount: 618 Pages: 2
Scientific Explanation on the Causes of Acid Rain
Acid Rain Acid rain is caused by extra amounts of sulphur dioxide and nitrogen oxides. Natural sources of sulphur oxides and nitrogen oxides do exist, but are balanced by nature. Normal rain reacts with alkaline chemicals from the region's bedrock that are in the air, soils, lakes, and streams. This neutralizes the rain. However, if rain is more highly acidic, then the natural neutralizing chemicals can eventually become depleted. This is what is happening with more than 90% of the sulphur an ... Ozone The earth"s atmosphere has 3 layers, the troposphere, stratosphere, and ionosphere. In the stratosphere at 10-30 kilometers above the Earth's surface there is a layer of ozone (03) that protects the earth from the sun's harmful UV radiation. ... Some chemicals, mainly CFC"s, can break down the ozone and thin this protective layer, when present into stratosphere. ... For example in areas of volcanic out gassing the ozone is decreases. The past 15 years show significant decreases in the ozone layer. ... Wordcount: 738 Pages: 3
Global Warming
Global Warming 5/1/00 Page #1 Global Warming Since global warming appeared during the last decade as a serious environmental issue, it has been the subject of a lot of debate.

Because of wide spread pollution, and negligence with the use of aerosols and other ozone depleting agents, the ozone la ... Because of wide spread pollution, and negligence with the use of aerosols and other ozone depleting agents, the ozone layer that shields the earth"s surface is steadily being depleted. This deterioration of the ozone layer is allowing for ultra violet radiation, emitted by the sun, to penetrate the protective ozone layer and bombard the earth"s surface with these carcinogenic rays. ...

Acid Rain4
Acid Rain The damaging effects of acid rain on society is becoming overwhelmed with great amounts of pollution from cars, factories and an large amounts of garbage. The immense amounts of sulphur dioxide put into the air causes high levels of acid in the atmosphere. When this sulphuric acid is absorbed into moisture in the air, then rain can be harmful to the environment. Acid rain is destroying lots of things in our environment. It is hurting lakes, air and thew rest of our ecosy ...

Global Environment
The Environment Whether it be through intensified media attention, or due to the efforts of prominent scientists and other members of society, we have become increasingly aware of the detrimental effects that technological advances in industry and agriculture have on the global environment. However, pollution is growing at such a rate that the cleaning up is too slow. This slowness is partly due to the fact that the threats we face are indistinct, since they come in the form of small parti ... It took the publicity of the dipleating ozone layer to encourage large chemical companies to begin a gradual phase-out of these harmful substances, even though scientists already discovered the effects of CFC"s and the ozone. It is said by Carl Sagan and many other scientists that ozone layer would take at least 100 years to repair itself if all damaging activity were to come to screeching halt. ...

Global Warming: The Greenhouse Effect
Global Warming - The Greenhouse Effect The "greenhouse effect" is a term that is used to refer to an atmospheric process. The greenhouse effect is the inability of long wave radiation to escape the atmosphere causing increased air temperature and increasing impurities in the atmosphere.

The Percentage of Essential Elements of Life
Today, we've realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth c ...
