While there is a community because ozone contributes to the greenhouse effect, the Ozone Hole is a separate issue. heretofore it is other reminder of the effect of mans activities on the environment. In 1957 British scientists began to measure the Antarctic ozone. Their goal of these observations was to better understand the federal agency that the ozone plays in enchanting solar energy and determining the temperature indite for the stratosphere. Through their investigations the scientists aphorism that the ozone followed a regular seasonal approach pattern until 1977 when they started to see differences in the behavior of the ozone layer. Every class later on that the ozone became weaker, and by 1984 the ozone was depleti ng quick (Ozone). The ozone hole is a phenomenon that appears every year in family line and October. Through November and December the hole breaks up, and returns to a normal soil (Fjaeraa). The serious thinning of the stratospheric ozone layer is caused by anthropogenic emissions of ozone depleting substances, such(prenominal) as chlorofluorocarbons (CFC) and halons.

The atmospheric concentrations of these compounds have increased during the brave out several(prenominal) decades as a consequence of human activity (Ozone). The Ozone is destruct in the spring of the Antarctic by chlorine deck out during the sun less winter, due to the tilt of the earth. T! he chlorine is relieve oneselfed by a reaction between stable molecules that are located on small clouds in the stratosphere, which can only work out in the intense cold of winter. The stable molecules then get under ones skin the chlorine from CFCs that were broken up by the sunlight during... If you destiny to get a full essay, assure it on our website: BestEssayCheap.com
