Protecting The Ozone Layer Essay

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. (Graedel 1998) More than 99% of the total atmospheric mass is concentrated in the first 40 km from Earth's surface. (Graedel 1998) Atmospheric layers are characterized in chemical compositions that produce variations in temperature. (Graedel 1998)
Here is a graph of the different layers in the atmosphere:

The troposphere is the atmospheric layer closest to the planet and contains the largest percentage of the mass of the total atmosphere. (Garcia 1994) It is characterized by the density of its air and an average vertical temperature change of 6 degrees Celsius (C) per kilometer. (Graedel 1998)
Temperature and water vapor content in the troposphere decrease rapidly with altitude. Water vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet's surface. (Graedel 1998) The troposphere contains 99 % of the water vapor in the atmosphere. Water vapor concentrations vary with latitudinal position. They are greatest above the tropics, where they may be as high as 3 %, and decrease toward the Polar Regions.
All weather phenomena occur within the troposphere, although turbulence may extend into the lower portion of the stratosphere. (Graedel 1998) Troposphere means "region of mixing" and is so named because of vigorous convective air currents within the layer. (Graedel 1998)
The upper boundary of the layer ranges in height from 8 km in high latitudes, to 18 km above the equator. Its height also varies with the seasons, highest in the summer and lowest in the winter. A narrow zone called the tropopause separates the troposphere from the next highest layer called the stratosphere. (Graedel 1998) Air temperature within the tropopause remains constant with increasing altitude.

The stratosphere is the second major stratum of air in the atmosphere. It resides between 10 and 50 km above the planet's surface. The air temperature in the stratosphere remains relatively constant up to an altitude of 25 km. (Graedel 1998) Then it increases gradually to 200-220 degrees Kelvin (K) at the lower boundary of the stratopause (~50 km), which is marked by a decrease in temperature. Because the air temperature in the stratosphere increases with altitude, it does not cause convection and has a stabilizing effect on atmospheric conditions in...

What´s The Ozone Layer? Essay

1448 words - 6 pages 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

2233 words - 9 pages have thinned the ozone layer and may now be starting to change the very climate system upon which we and all other life on Earth depend. In effect, we are experimenting with the future, but unlike performing a laboratory experiment, which can be scrapped and begun anew if it fails, altering the climate is something that cannot be easily undone. Whatever happens, we shall all be forced to live with the consequences for a very long time. The author of

Lastly, a common evidence of global warming is the failure of cultivated crops. Many lands have dried up and have fissures because there is no water left especially on the season of El Niño which lead to hunger and increase in demand of food. The Ozone Layer is a

The growing problem of its depletion is being researched heavily all over the world, and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be

Depletion of the Ozone Layer: Its causes, effects, and possible solutions

2740 words - 11 pages The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will give vital information on how pollution affects the

844 words - 3 pages 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
