Carbon Dioxide Ozone Layer
924 wordsA. Who makes up most of the pollution B. Who and what is harmed by pollution Conclusion: We need to use renewable resources and finding uses for waste products instead of creating pollution by throwing them out. Our environment is a crucial part of our lives, and we must learn how to treat it correctly. Without it we would not be living. We need to become more aware of the circumstances that are going to take place if action is not taken. We need to stop making emphasis on what will make us more...

Chlorofluorocarbons Cfcs Nitrogen Oxides
1,336 wordsDramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970 's by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station. The Halley Research Station BAS research stations in the Antarctic Rumor has it that when the first measurements were taken in 1985, the drop in ozone levels in the stratosphere were so dramatic that at first the scientists thought their instruments were defective....

Atomic Bomb Was Dropped Hundreds Of Thousands
1,609 wordsIt began in the desert of New Mexico on July 16, 1945, with the first U. S. atomic test called Trinity. The device was comprised of 19, 300 tons of TNT explosive. There was an intense light that brightened the distant mountains, a sudden wave of heat, and then a tremendous roar as the shock wave echoed in the valley (Bolt 1). This was the first atomic test recorded in the history of the world. The man who invented the atomic bomb was physicist Albert Einstein. Two months after Einstein's incredi...

Speed Of Light Time Of Day
1,333 wordsOur view of the sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interac...

Effects Of Acid Rain Sulphur Dioxide
868 wordsThe 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 ecosystem. Acid rain is killin...

Piece Of Paper Oxygen Molecules
1,524 wordsIn 1839, a German scientist Christian Schonbein was a professor of chemistry at the University of Basel in Switzerland. In addition to his teaching duties, he regularly performed secret experiments in hopes of finding out which substances make up the Earth's atmosphere. So Schonbein combined and separated a number of liquids and gases. During one of these experiments, Schonbein passed an electric charge thought a glass beaker of water, be noticed a very familiar odor. He first thought it was the...

Fossil Fuels Greenhouse Gases
1,295 wordsThe importance of the greenhouse effect was just conceived in the mid-twentieth century. "For billions of years, cosmic forces shaped Earth, and land and air coevolve at an almost inconceivably slow pace to create a climate in which human beings and other creatures could flourish. " (Francesca Lyman). Now, for the first time, humanity has the power to change the global climate. By releasing the huge amounts of carbon stored in fossil fuels over millions of years, we are distorting the natural ca...

Greenhouse Gases Ultraviolet Radiation
421 wordsDiscovery of the hole in the ozone layer showed that human activity has a major impact on Earth. The destruction of ozone in the stratosphere high above the planets surface has been brought about as the result of the widespread use of chemicals, which under normal conditions are chemically inert and harmless. Ozone occurs at all levels in the atmosphere, but most of it is found in the stratosphere, between about 15 - 50 kilometres above the Earths surface. Even there it occurs in minute concentr...

Ozone Layer Atmosphere
407 wordsCould an exploding star have been responsible for the death of the dinosaurs? This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth? s atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was observed, people often thought a new star ...

Millions Of Years Ozone Layer
1,312 wordsMy views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously, nor do I believe that the earth is so delicately balanced. I don? t believe that the earth and its ecosystem are fragile. Many radical environmentalists do, they believe man can come along, all by themselves and change everything for worse. After hundreds of millions of years, they believe that we are the last two generations of human existence. And they think we can destroy ...

Millions Of Dollars Ozone Depletion
946 wordsHalon an extinguishing agent was developed after World War II for the protection of aircraft engines. Several types were developed, and several were banned and discontinued such as halon 104. Other types were halon 1202, halon 1211, halon 1301, and halon 2402, which was never widely used in the United States due to its high toxicological concerns. Halon type 1101 was widely utilized for aircraft engines. The two most common types being; halon 1301 bromotrifluoromethane, C BrF 3, which is most co...

Upper Atmosphere Ozone Layer
591 wordsOzone, pronounced OH Zone, is a form of oxygen that is present in the earths 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. Photochemical p...

Ultraviolet Rays Uv Rays
633 wordsThe ozone layer shields the earth from most of the harmful radiation and light comming from the sun. The ozone reflects and absorbs the ultraviolet rays that try to come in. Without this kind of protection, all living things will be effected by these UV rays. Skin cancer develops in most living mammals as a cause of an overabundance of the suns ultraviolet rays. The ozone layer is located in the earths stratosphere. The ozone layer is located from about fifteen-to-thirty kilometers above the ear...
