Earth This will cause humans suffering like skin cancer and UV radiation may kill plankton. CFCs will also cause global warming. We should take action to protect our ozone layer.
Ozone is a toxic, gaseous, bluish molecule which has a strong odour and contains three Oxygen atoms with the formula O3. An excess of UV radiation increases the risk of contracting forms of skin cancers or ocular diseases.
It may also weaken the natural immunity of human beings and animals. Although near the surface, in the air we breathe, ozone is a pollutant, which in large amounts causes damage to huamans, animals and plants.
UV rays are short-wave, energetic electromagnetic radiation released by the sun. Much of the solar ultraviolet radiation is absorbed in the stratosphere, where the production and destruction of ozone is involved , thus this cycle has kept the ozone stable.
UV-B can be tremendously harmful to any form of life because this radiation can enter cells and destroy the DNA. Damage to DNA which carries the characteristic information of a species from generation to generation would consequently mutate the individual genes in distressing and even fatal ways.
UV rays can cause non living things such as paints, plastics and various other materials to decay rapidly. The effects UV rays have on all living and non living things on earth are endless.
UV rays would cause all types of skin cancer: Melanoma, Basal Cell and Squamous cell which are all extremely damaging to humans. UV rays can also cause an increase in eye cataracts causing clouding of the cornea. The ozone layer is important to our health as it acts as a sunscreen, blocking out most of the UV rays which cause harm to plants and humans by causing various diseases stated above.
Not only could the UV rays cause harm to humans but it could also produce a reduction of the efficiency in Photosynthesis in plants and also of ecological systems such as agriculture, hence our crops, food, soil and more would be not as productive as it now is, causing issues in the doof chain.
Even though the ozone layer is an invisible shield, scientists have found numbers of ways to calculate how much ozone is in the atmosphere. An instrument called the Spectrometer, which was discovered by Mr. Gordon Dobson, measures the total ozone from the ground by measuring the concentration of solar UV radiation at four wavelengths in which two of those wavelengths are absorbed by the ozone and two of which are not .
Ozone is what is known as a trace gas, meaning there is very little of it in the atmosphere; out of every million molecules of gas in the atmosphere, less than ten are ozone. Another effective way the ozone could be measured is to use helium filled balloons that carry measuring instruments into the atmosphere and transmit information back to Earth.
The ozone hole over Antarctica gradually became larger between August 12th and November 11th as shown in this animation http: As the months progressed it could be seen that the ozone was only DU in the grey dark reddish zone . There are signs that the ozone layer is getting thinner all over the planet.
The loss of the ozone layer occurs when more ozone is being destroyed then nature is creating.
Free radicals free chlorine atom are uncharged atoms or molecules with unpaired electrons or an open shell design.[tags: Ozone Layer Environmental Essays] Research Papers words (3 pages) Essay about The Ozone Layer - The Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause.
Its existence is crucial for life on earth as we know it, because the ozone layer controls . Free ozone layer papers, essays, and research papers. Free geology papers, essays, and research papers. Geology: The Study of the Earth - Erosion occurs when wind or water blow/wash away the topmost fertile layer of soil.
Published: Mon, 5 Dec The introduction of harmful waste materials, other forms of contamination which are a hazard to the life sustaining atmosphere of the planet earth is commonly known as pollution. "Requiem for Methuselah" is a third season episode of the American science fiction television series Star Trek, first broadcast on February 14, Volcanic Eruptions and Global Climate Change - Volcanic Eruptions and Global Climate Change Abstract There has been much debate in recent decades over how much volcanic eruptions contribute to global climate change, the destruction of the ozone layer, and global warming.
