1. Describe the temperature and pressure patterns in the figure E-1?
In the layer troposphere the temperature decreased, because it starts from 2c and decreased to -4c. In the layer stratosphere the temperature increased from -41c to -39c and from -39c increased to 2c. In the layer mesosphere decreased from 2c to -50c. In the layer thermosphere increased from -50c to 122c. The pressure in the layer troposphere started decreasing from 40 to 0. In the layer stratosphere still decreasing from 0 to -40, and for the mesosphere and thermosphere stays at the -40c.
2. How thick would 200 DU of ozone be?
The thick would be 2.
3. How is ozone formed naturally?
It is formed naturally by chemical reactions.
4. How is ozone destroyed and destructed naturally?
Stratospheric ozone is destroyed by the chlorine contained in certain chemicals (other substance also “eat” ozone, but chlorine is the most important). Many of these chemicals, called chlorofluorocarbons.
5. What was the Montreal Protocol (1987)?
The Montreal protocol on substance that deplete the ozone layer was designed to reduce the production and consumptions of ozone.
6. Explain the Arctic Ozone?
Area that may affected by formation of arctic ozone is the yellow area within the red circle.
7. Explain the history of the ozone hole from 1980 to 2012? Give your idea about what happening?
In the 1980's the first measurements of this loss were actually documented. In 1984, when the British first reported their findings, October ozone levels were about 35 percent lower than the average for the 1960s. When the first measurements were taken the drop in ozone levels in the stratosphere was so dramatic that at first the scientists thought their instruments were faulty. The ozone hole reached its maximum size Sept. 22, 2012 covering 8.2 million square miles (21.2 million square kilometers), or the area of the United States, Canada and Mexico combined. The average size of the 2012 ozone hole was 6.9 million square miles (17.9 million square kilometers).
8. How does the Sun’s Effect on the ozone layer?
As in the pressure from layer troposphere is high and decreased when it goes up to the space.
