What happend to the ozone layer in the last century?
In the last century the ozone layer was depleted. It is also termed as ozone hole.
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.
How long does ground level ozone last in the atmosphere?
A few hours. The half-life of ozone is dependent on temperature and water vapor, increases of either will shorten its lifespan.
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.
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".
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.
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.
How is ozone in the stratosphere the same as the troposphere?
No. The ozone is stratosphere is good ozone. The ozone in troposphere is bad ozone.
What cause troposphereic ozone?
The tropospheric ozone is bad ozone. It acts as a pollutant.
Is the ozone layer depleting over antacrtica?
The ozone layer depletes everywhere. The poles develop an "ozone hole" in late winter / early spring at that pole. The hole has nothing to do with depletion, it has likely occurred every year for the last 500 million years.Depletion shows up in how soon the hole starts, how long it lasts, and how little ozone is present in it.
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.
