Ozone Layer

Ozone Layer
Ozone, pronounced OH-Zohn, is a form of oxygen that is present in the earth?s 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



The Poisoning of Our Ozone Layer

The Poisoning of Our Ozone Layer
The poisoning of the Earth?s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone?s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem and preserve the ozone layer. Ozone is a pale blue gaseous form of oxygen, in chemical form it is also known as O3. Ozone can be beneficial or harmful depending on its location in the Earth?s atmosphere.



Essay in Hindi

For a native English speaker, writing an essay in Hindi may be a big challenge. This is because the structures of the two languages are somehow different. But sometimes, there are chances when students will be required to write an essay in Hindi for the purpose of learning the language more. We are not going to talk about the students in the general population of a school. There are only a few students who are concerned with this type of an essay.



Essay in Hindi

Did you enroll in a language class? To be more specific, are you taking a Hindi language course? If you answer yes to both questions, then most probably you will soon be writing an essay in Hindi. Most teachers require their students to write an essay during the course of the semester or academic year. Essay writing is technically one of the best ways to test the communication and writing skills of the students.



Stratosphere Facts

Stratosphere Facts
Stratosphere is one of the five layers of the earth's atmosphere. Acquaint yourself with some stratosphere facts, through this article.



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. Over exposure to UV causes damage to dna in cells and increases chances of mutations. It can reduce the metabolism of plants and algae as well as increasing chances of skin cancers and cataracts in animals and humans. Its also believed UV radiation may do harm to the immune system.

If you are a student in college enrolled in a Hindi class, then most probably you will be writing an essay in Hindi. This is one task that you should complete regularly to familiarize yourself with the terms and words of the language. Hindi and all other language electives in college are not provided to all students. If one is interested to take the course, then he needs to undertake the essay instructions coming from the professors. Aside from oral exams, written exams and projects are also essential.



Ozone Season Just Ahead

Ozone Season Just Ahead
With ozone season just around the corner, big cities everywhere are getting worried about low visibility and magnified allergies. The season begins Monday, May 1st and extends through September 30th. Jilayne Jordan, Spokesperson for the Georgia Department of Transportation says that, Elderly people, kids with asthma or allergies and people who exercise outdoors that when there?s a smog alert day, it?s extremely hard on the lungs. Mark Ressler, Senior Meteorologist at The Weather Channel, says weather can worsen the problem.



Ozone

Ozone
Ozone is an important molecule in maintaining the homeostasis in the
environment. Ozone, the molecule O3, makes a layer in the stratosphere,
situated 10 to 15 kilometers from the earth?s surface. The dioxide
molecule, O2 and Oxygen atom O, collide with each other result in the
formation of Ozone, O3. In this reaction, the molecule O3 contains an excess
of energy. Once the molecule is formed, it is not stable enough to last
long. The energy-rich O3 molecules discards the excess energy by colliding
with another atom or molecule and transferring the energy in the form of
heat. In the results of the decomposition of ozone into O2 and O in the
ozone layer, solar radiation is absorbed. This process of the chemical bond
breaking causing the absorption of a photon by a molecule is called
photodissociation. Radiation with sufficient intensity, is capable of
separating the O3 molecule, resulting in photodissociation. The cyclic
process formation and decomposition of ozone provides a shield against
ultraviolet radiation that enter the earth?s atmosphere. If it were not for
the chemical reaction of radiation and ozone in the stratosphere, these
high-energy photons would penetrate the earth?s surface. The ozone layer
absorbers about 99% of the harmful radiation which makes it possible for
animals and plants to live on the planet.



The Ozone Layer, Greenhouse Effect, and Global Warming

The Ozone Layer, Greenhouse Effect, and Global Warming
Energy is the capacity for doing work, generating heat, and producing light. We use energy from the time we wake up until the time we go to sleep at night. Without energy we would not be able to perform the daily functions of life. Although energy is useful to us, energy has a down side. One of the topics discussed in class was electromagnetic energy. During the lecture on electromagnetic energy, the concept of the ozone layer and global warming was discussed. We briefly talked about how the ozone layer was disappearing because of the increasing amount of greenhouse gases. These topics of electromagnetic energy and the atmosphere struck me. Therefore, I decided to explore the subjects of the ozone layer, greenhouse effect, and the dangers of global warming. Electromagnetic energy travels by wavelengths of radiation and moves at the speed of light
