what factors contribute to the destruction of the ozone layer?

Answer 1

The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), hydroxyl (OH), atomic chlorine (Cl) and bromine (Br). While there are natural sources for all of these species, the concentrations of chlorine and bromine have increased markedly in recent years due to the release of large quantities of manmade organohalogen compounds, especially chlorofluorocarbons (CFCs) and bromofluorocarbons. These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 10,000 ozone molecules. Ozone levels, over the northern hemisphere, have been dropping by 4% per decade. Over approximately 5% of the Earth's surface, around the north and south poles, much larger (but seasonal) declines have been seen; these are the ozone holes.

Answer 2

There is nothing wrong with the ozone layer. The holes form at the poles at different times. The ozone layer is created by the solar winds collide together at very high altitudes. Most of the compounds that are said to deteriorate it is too heavy. the old story of CFC cant be true. They say that at almost the same time each year the CFC get together and go for a vacation at the south pole WRONG u are giving intelligence to the CFC molecules.

Answer 3

The addition of CFC's Chlorofluorocarbons which break up the ozone into oxygen is what contributes to the destruction of ozone layer.

Answer 4

Essentially, one: the chloroflourocarbon molecule. Used as a refrigeration agent (without which, more food would spoil and more people would starve), it also has the peculiar characteristic of a catalyst, converting two of the O3 into three of the O2. While we breath the O2, the O3 is what blocks the solar radiation. Meanwhile, the solar radiation is up there catalyzing more O3 as I type. So we're in a kind of race. The trick is to lose that race without killing a bunch of poorer humans by not letting them keep their food.
