  • Slogan In Hindi On Depletion Of Ozone Layer

    The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer, also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man, animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there, the harmful ultraviolet rays will reach to the...

  • The Ozone Layer Depletion

    Every time 1% of the ozone layer is depleted, 2% more UV-B is able to reach the surface of the planet. So in short, without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen, without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth, there are a few groups who think that the ozone layer is a “myth” aka doesn’t...

  • 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...

    How does the atmosphere affect conditions on Earth? What is Earth's atmosphere composed of? How do pressure and density vary with altitude? What are the characteristics of the major layers of the atmosphere?  Important Terms atmosphere air pressure barometer troposphere weather stratosphere ozone layer mesosphere thermosphere ionosphere aurora   At 8848 meters (29,030 feet) above sea level, Mount Everest is the highest mountain in the world. In 1952 Edmund Hillary, a New Zealand...

  • Ozone

    thin layer of gas called atmosphere surrounds the Earth. The atmosphere serves two important purposes: it is a filter for the suns dangerous ultraviolet radiation rays and keeps the heat, necessary to maintain life on earth, within the stratosphere (Vorlat 361). Ultraviolet light is incredibly dangerous to all the organisms within the Earth's ecosystem because it causes skin cancer, effects the immune system, and harms plant and animal life. For that reason the atmosphere and the ozone layer within...

  • Layers of the Atmosphere

    Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes), • chemical composition, • movement, and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical composition, movement, and density occur. Troposphere The troposphere begins at the Earth's surface and extends from 4 to 12 miles (6 to 20...

  • Ozone Deterioration

    Ozone Deterioration The Causes of Ozone Depletion Scientific evidence indicates that stratospheric ozone is being destroyed by a group of manufactured chemicals, containing chlorine and/or bromine. These chemicals are called "ozone-depleting substances" (ODS). ODS are very stable, nontoxic and environmentally safe in the lower atmosphere, which is why they became so popular in the first place. However, their very stability allows them to float up, intact, to the stratosphere. Once there, they are...

  • ozone hole

    Before I talk about the ozone hole, I would like to talk about what ozone is. Ozone is a gas that is made of three oxygen atoms and it’s found up in the atmosphere (stratosphere layer). These three oxygen atoms are so important to us because they protect us from UV radiation. When UV rays try to come to earth they come across these three oxygen atoms and hits them, converting them into oxygen gas (O2) and one more oxygen (O). That prevents the UV rays from coming to earth. Ozone hole means that it’s...
