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 radiation (in particular UV-B) that would otherwise reach our planets surface....   [tags: essays research papers fc]

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 on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found t...   [tags: essays research papers]

Holes in the Ozone Layer

- Holes in the Ozone Layer Ozone, 03 is a highly important component of the earth's atmosphere. Close to the ground ozone, is produced by the action of light on exhaust fumes and so concentrates in areas of heavy traffic. In this was it can be a pollutant, it corrodes metal, can inhibit plant growth and cause irritation to the lungs and throat. Up in the stratosphere though, about 15-50km above the earth surface, ozone is beneficial as it intercepts much of the suns UV (ultraviolet) radiation that would otherwise reach the earth....   [tags: Papers]

The Effect Of Our Ozone Layer And Climate Change And 2

- For the last few years I keep reading on various news agencies about Global Warming. Some say that it is a myth and it was created to assist certain businesses in thriving with different energy technologies. So is it something to be truly worried about or is it just a ploy. We are going to investigate the truth behind all of this, especially 1. The effect of our ozone layer and climate change and 2. How the human being is playing an impact on it. According to the World Metrological Organization which met two days ago on July 21, 2016 stated “the first six months of this year were the hottest on record”....   [tags: Greenhouse gas, Climate change, Carbon dioxide]

Depleting Ozone Layer And Increasing Levels Of Ultraviolet Radiation

- Sunblock Opposed to Sunscreen Through the depleting ozone layer and increasing levels of ultraviolet radiation within our atmosphere, skin cancer has risen as one of the major problems within contemporary society. Unfortunately, UV rays increase the risk of obtaining skin cancer since they permanently alter the DNA structure within our cells, creating a vast array of mutated cells. Research has shown that melanoma is considered the most serious type of skin cancer due to the development of dark spots on the skin, which develop in basal cells at the base of the epidermis caused by the exposure of ultraviolet rays....   [tags: Ultraviolet, Sunscreen, Sunburn, Sun tanning]

The Effects Of Fossil Fuels On The Environment And The Ozone Layer

- In 2007, the world consumed 5.3 billion tons of coal, 31.1 billion tons of oil, 2.92 trillion cubic meters of natural gas, and 65,000 tons of uranium. All of these energy needs could have been met with only 6,600 tons of thorium, an abundant, slightly radioactive element found in the Earth’s crust. We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out of fossil fuels....   [tags: Nuclear power, Coal, Uranium, Light water reactor]

The Ozone Layer Shields Us and Saves Our Lives

- ... Solar energy is inexhaustible and cheaper than ever, now powering everything from portable radios to homes, stores and neighborhoods. Geothermal energy on a smaller scale is through a geothermal heat pump, which exploits the temperature difference between the earth's surface and the air. The state of Maine gets 22 percent of its electricity from hydro-power. These are proven techniques geared toward the conservation of energy, promoting a healthier earth in our near future. Unlike many renewable sources of energy, fossil fuels are relatively less expensive to produce....   [tags: radiation, energy, atmosphere]

Protecting the Ozone Layer

- Orbiting above the Earth, an astronaut can look down on our home and see the thin blue ribbon that rims our planet. That transparent blanket -- our atmosphere -- makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by narrow transition zones which is the atmosphere. (Graedel 1998) The upper boundary at which gases disperse into space lies at an altitude of approximately 1000 kilometers above sea level....   [tags: Papers]

ozone layer

- ozone layer Summary of Learning of the Ozone Experience On the 16th of September 1987, negotiators meeting in Montreal finalized a landmark in international environmental diplomacy: the Montreal Protocol on Substances That Deplete the Ozone Layer. The Successful Conclusion of the negotiations in Montreal was widely hailed at the time as a historic even. As the protocol was the most ambitious attempt ever to combat environmental degradation on a global scale. In the 10 years since that meeting in Montreal, the accord has set in motion myriad actions by national governments, international organizations, scientists, private enterprises, and individual consumers....   [tags: essays papers]

Ozone Layer Depletion

- Ozone Layer Depletion Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by various reactions with other components in the air. The next result of these natural processes is the so-called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen. However, an ordinary molecule of oxygen contains two atoms....   [tags: Papers]
