What else can I help you with?
What are some suggested causes to the depletion of the ozone layer?
The ozone layer was depleted from the actions of CFCs (chlorofluorocarbons) released into the atmosphere last century. CFCs were used in aerosols and fridges and escaped into the air where the winds gradually moved them all around the world and up to the ozone layer. There chlorine broke from the CFCs and destroyed the ozone.
Why are there more people getting skin cancer now than in the last century?
The o-zone layer is tons weaker. That is why we have global warming ect too. The ozone layer weakening is due to pollution
What layer is the ozone a part of?
You can find ozone in any layer of the atmosphere, but in the lower layers it does not last long. The so-called ozone layer is in the lower portion of the stratosphere, at a height where it takes a long time to dissociate.
What continent has a hole in the ozone layer been growing larger and lasting longer over the last 20 years?
The ozone layer is not growing larger. The ozone hole is getting larger. It is getting larger over Antarctica.
What is the role of the ozone layer and what causes changes to occur?
The ozone layer protects the earth from harmful UV rays from the sun. All those CFC's actually tear holes in the ozone layer, but they take 50 years to reach there. So the last CFC's in the atmosphere, sprayed in 1972, won't even start tearing apart the ozone layer till 2022!
What is causing the ozone layer to get smaller?
Chloroflorocarbons (CFCs) did. From what i've heard the ozone layer is starting to slowly heal up again. According to a report (2011) by the Scientific Assessment Panel of the U.N. Montreal Protocol on Substances that Deplete the Ozone Layer, the ozone layer has, over the last decade, reached a turnaround point. It is no longer decreasing, but it is not yet increasing.
Over what continent has a hole in the ozone layer been growing larger and lasting longer over the last 20 years?
The ozone layer is not growing larger. The ozone hole is getting larger. It is getting larger over Antarctica.
What does ethanol do to the ozone layer?
Burning ethanol releases Carbon Dioxide (CO2), a greenhouse gas which is causing global warming. It has very little to do with the ozone layer, which was damaged last century by chlorine and bromine from CFCs (chlorofluorocarbons), released from aerosols and refrigeration.
How has the ozone layer changed over time?
It was nonexistent before there was significant oxygen in the atmosphere. After the Great Oxidation Event, we developed our ozone layer, complete with annual ozone "holes" at each pole. We have evidence of sporadic events punching holes in the ozone layer from time-to-time. Since the 1700s, the ozone layer has been getting steadily thinner. This gets us to "current events".
Do air planes fly in the air do stop the ozone hole from growing?
Yes, partly, for the last ten years, these county's United States, Russia, Canada, China, and India. They believe if they can break down the gases in the air that destroy the ozone layer. In the last year, the United States have found something close to help the ozone layer. About five mouths ago, Russia said that they may have found something as well that break down the ozone layer.
What happend During the last half of the twentieth century the population of Latin America?
It has more than doubled.
For how much more years will the ozone layer last if the depletion continues at this rate?
When have you ever known anything to continue at the same rate? The ozone hole was smaller this year than in 2006. So maybe we have a grip on enough bad things to allow the ozone layer to get thicker farther from the equator.
