Depletion of the Ozone Layer
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research

Our Radiant Planet: Depletion of the Ozone Layer
Our 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 35km 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

The Ozone Layer
The Ozone layer Since the 1960's the ozone layer has greatly depreciated because of man made compounds. The thinning of the Ozone layer causes many problems to the Earth's environment and animals. When the Ozone layer thins out more UV rays reach the Earth's surface from the sun. Three effects this can have is Skin cancer, reduction in the production of crops and the destruction of phytoplankton. There are many different compounds that cause the

The Ozone Layer
The word Ozone originates from the Greek word "ozein" meaning 'to smell'. Ozone is a toxic, gaseous, bluish molecule which has a strong odour and contains three Oxygen atoms with the formula O3. The ozone is situated in the in the part of the atmosphere called the Stratosphere about 12-35 km above the Earth's surface [1]. Ozone is formed when an oxygen molecule (O2) in the stratosphere is broken into two oxygen atoms (O +

Ozone Depletion
Ozone Depletion A Case for "Ignoring the Facts" Ozone forms a layer of the earth's atmosphere that protects us from the sun's deadly ultraviolet rays. During the last decade there has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer. Although there has been no evidence of any CFC destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive order set

Ozone Depletion
"In nature there are neither rewards nor punishments--there are consequences." Robert G. Ingersoll (1833 - 1899) The ozone layer plays an important role in the atmosphere. It protects life on earth from the full force of the sun's cancer-causing ultraviolet radiation. However, many household products and appliances release substances to the atmosphere that causes the hole in the ozone layer. Chlorofluorocarbons (CFCs), used as refrigerants and aerosol spray propellants, is the main cause of ozone

Issue on Ozone Depletion
Ozone Depletion The ozone layer is a layer in the stratosphere, which is about 15 and 30 kilometers in altitude, containing a relatively high concentration of ozone. The upper portion of the earth's atmosphere is called upper-level ozone. This layer of the atmosphere, extending from about twelve to twenty four miles above the planets surface, and is known as the stratosphere. The ozone layer protects the Earth by absorbing some wavelengths of solar ultraviolet radiation

The Ozone Depletion Phenomenon
Summary Like an infection that grows more and more virulent, the continent-size hole in Earth's ozone layer keeps getting bigger and bigger. Each year since the late 1970s, much of the protective layer of stratospheric ozone above Antarctica has disappeared during September, creating what is popularly known as the ozone hole. The Antarctic hole now measures about 9 million square miles, nearly the size of North America. Less dramatic, still significant, depletion of ozone levels

Ozone Depletion
Essay ozone depletion is a serious problem presently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is necessary to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, manufacturing

To Hell with the Osi 7 Layer Model
To hell with the OSI 7 Layer Model Back in the 1980's, when all music sucked and men dressed like fags, a bunch of sissy Europeans got together in a passionate effort to overstandardize computer networking. They created this thing called the Open Systems Interconnection (OSI) networking suite.

Science of Ozone
THE SCIENCE OF OZONE Ozone, though similar to oxygen chemically, is composed of three molecules of oxygen and is usually blue in color with a very strong odor. The atmosphere contains less ozone than the common oxygen. While out of every ten million air molecules, there exist about two million molecules of normal oxygen and only three molecules of ozone. Most of these ozone molecules are typically concentrated in the Stratosphere, the atmospheric layer that
