The Ozone Hole and Petroleum Release
Introduction
The atmosphere can be divided into four layers based on temperature variations. The closest layer to the Earth is called the troposphere and it extends from Earth's surface up to 7 km (23,000 ft) at the poles, and about 17-18 km (56,000 ft) at the equator. Above this layer is the stratosphere which extends from the top of the troposphere to about 50 km (32 mi; 170,000 ft). The upper boundary between troposphere and stratosphere is known as the tropopause. Temperature variations in the four layers are due to the way solar energy is absorbed as it moves downward through the atmosphere. The Earth’s surface is the primary absorber of solar energy. Some of this energy is reradiated by the Earth as heat, which warms the overlying troposphere. The global average temperature in the troposphere rapidly decreases with altitude until the tropopause, the boundary between the troposphere and the stratosphere.
The temperature begins to increase with altitude in the stratosphere. This warming is caused by a form of oxygen called ozone (O3) absorbing ultraviolet radiation from the sun. Ozone protects us from most of the sun’s ultraviolet radiation, which can cause cancer, genetic mutations, and sunburn. Scientists are concerned that human activity is contributing to a decrease in stratospheric ozone. Nitric oxide, which is the exhaust of high-flying jets, and chlorofluorocarbons (CFCs), which are used as refrigerants, may contribute to ozone depletion.
At the stratopause, the temperature stops increasing with altitude. The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude.
At the mesopause, the temperature begins to increase with altitude, and...

Environmental Risk Perception: Ozone Hole Diminishing Essay

- Environmental Risk Perception Ozone Hole Diminishing This article states that the ozone hole is diminishing. The credit for this good news is the phasing out of the ozone-depleting chemicals sponsored by the Montreal Protocol (Ozone hole diminishing, Nov). According to this article, the hole reached a peak of 25 million square kilometers, coming down from 28 in previous years since 1998 up to 2006. The article emphasizes the fact that ozone-depleting gases are still being used. The article continues by stating that according to the World Meteorological Organization, the planet will come back to pre-ozone hole conditions between 2060 and 2075 (Ozone hole diminishing, Nov)....   [tags: Ozone Depletion, Climate Change]

Essay on What´s The Ozone Layer?

- The ozone layer is a deep layer in the Earth’s stratosphere that has an altitude of about 6.2 miles and contains a high concentration of ozone molecules. The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. The Earth’s atmosphere is composed of several layers, but the layer that we live in - the “troposphere” – is where most weather occurs. Above the troposphere is the stratosphere which is where most of the effects caused by ozone holes and global warming originate....   [tags: ultraviolet rays, ozone moleculas]

Ozone Depletion and Industrial Output Essay

- Ozone Depletion and Industrial Output For years, we have heard about the ozone crisis: that because of industrialization and the lack of pollution-consciousness by our industries, governments, and academia, we have put so many environmentally harmful products into the atmosphere that our ozone – the good kind, the kind that protects us from harmful UV radiation – is becoming dangerously damaged. It is becoming thinner and developing holes, like the large hole over Antarctica. Predictions made expected the ozone hole to continue to increase and for the general thickness to get continuously thinner, so that the harmful UV rays of the sun would pass right through our atmosphere an...   [tags: Ozone Layer Environmental Essays]

Depletion Of The Ozone Layer Essays

- Due to human activity, our planet has been slowly depleting over the years and has been recently increasing. The problems of global warming and climate change have risen due to the carelessness of the human population. Some of the problems happening to the planet is depletion of the ozone layer, the increase of endangered animals, and a decrease of natural resources. Many people fail to realize that our species is the reason this planet is dying. Increasing populations mean a higher demand for resources which will not be here forever....   [tags: Oxygen, Carbon dioxide, Ozone depletion]

Petroleum Engineering At Louisiana State University Essay

- As we all know, global commodities markets are in disarray. The Greek debt crisis, China 's stock market crash, the potential for Iranian sanctions to be lifted, and OPEC 's outright refusal to cut production has left us in a world where a $105 barrel of oil doesn 't write the rules in this industry anymore. Unfortunately, the job market is currently looking quite grim for college graduates in the field of petroleum engineering. However, I am determined to stay with the oil industry and attend graduate school in the pursuit of furthering my dream....   [tags: Petroleum, Natural gas, Petroleum industry]

The Ozone Essay

- The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone isharmful....   [tags: Essays Papers]

Essay Ozone

- Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The ozone layer is a small residual amount of ozone concentrated in a band in the upper atmosphere....   [tags: Ozone Layer Oxygen Environmental Essays]

Ozone Depletion Essay

- Ozone Depletion The world's ozone is depleting on a daily base. Individuals and industries are to blame. If we don't slow down what is being introduced to the atmosphere, the effects on humans and the earth will be devastating. We must stop killing the earth's ozone by watching what CFC's get released, car pooling to control automobile emissions, and stop industries from polluting our atmosphere. The problems with a depleting ozone layer are an increase in skin cancer, global warming of the earth, and a greenhouse effect on the world....   [tags: Papers]

Essay about 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....   [tags: essays papers]
