Ozone Layer

The ozone layer in the upper atmosphere has a vital role in protecting the inhabitants of earth. It blocks the harmful ultraviolet radiations which could be very fatal.

Chlorofluorocarbons

The US is trying to stop the damage in stratosphere. They are doing this by banning CFC's.

The immediate effects of depletion are UV entering. They cause plankton death.

It doesn't. The ozone in the upper atmosphere screens out most of the ultraviolet radiation that reaches us from the sun, protecting life on earth from its harmful effects. However, by the 1980s, the amount of ozone in the upper atmosphere had fallen to such a dangerously low level that a hole in the ozone layer had opened up over most of the continent of Antarctica. The reduction in ozone levels was shown to be caused by the manufacture and use of certain gases, such as chlorofluorocarbons, in airconditioning units and refrigerators. When released into the atmosphere, these gases combined with the atmospheric ozone, reducing the natural level. Urgent action was undertaken by governments around the world, to ban the manufacture of these gases. Only now are atmospheric levels of ozone beginning to return to normal.

CFC's are a major problem. It is because they deplete the ozone.

Ozone does not mean anything. It is just the name given to the cmpound O3.

yes.... S.L.

The ozone is in better shape, more stable anyway. The hole changes size/shape over time and with season. Bear in mind though, 'better' and 'stable' still means there's a hole the size of North America in it during September. (over 25,349,000 Sq Km)

no.

High intensity UV radiation can be harmful to human skin, causing sunburn and potentially skin cancer. It can also damage materials such as plastics, paints, and fabrics. Protective measures such as wearing sunscreen, sunglasses, and clothing that blocks UV rays are important when exposed to high intensity UV radiation.

I couldn't find the answer, but in Nascar, this might give you a hint:

The NASCAR road courses always bring into discussion just who the best road racer in NASCAR is. Immediately, the first two names to roll off of the tongue are Jeff Gordon and Tony Stewart (with a combined 15 wins on the tracks that go right and left). From there, the attention usually shifts the "ringers" (Ron Fellows and Boris Said) or even to "in-series ringers" (Robby Gordon and Juan Pablo Montoya).

Ozone layer protects us from UV rays. Greenhouse gases cause global warming.

CFCs were banned because they were causing ozone depletion,allowing hazardous UV rays to penetrate earth's atmosphere.

It protects us from the UV rays of the sun. It is present in the stratosphere.

Ozone is characterized as bad in the troposphere. It is a pollutant and a greenhouse gas.

uv radiation destroys vitamin D

Without different gases there will be no air, if there is air, how can oxygen travel?

Ozone eaters are CFC's. They should be stopped and HCFC's be used.

The thinning of the ozone layer occurs over each pole during the winter months at that pole. Countries very near the South pole could experience some reduction of their ozone during the winter months during years with unusually high solar activity.

See the related questions section below.

They do harm the ozone. But the amount is very less.

Polar bears have a thick layer of fat, called blubber, that helps them stay warm in their Arctic habitat. This layer of fat also serves as a source of energy when food is scarce. The blubber can make up about one-third of a polar bear's body weight.

People do make a difference. Banning of CFC and planting more trees would lead to less depletion.
