Derivatives of this anion are explosive and must be stored at cryogenic temperatures. Ozonides for all the alkali metals are known.
Ozone Layer Depletion What is ozone? Ozone is a gas made up of molecules that are formed by three oxygen atoms. Its molecule formula is O3. Ozone is formed when the sunlight hits oxygen molecules O2 and breaks them up into individual atoms.
These individual atoms then join up with O2 molecules and make O3, or ozone. What is the ozone layer?
|Causes and Effects of Ozone Layer Depletion That are Painfully True||Overexposure to UV light can lead to skin effects that resemble premature aging, as well as skin lesions known as Actinic keratoses. Cataracts can develop from UV exposure, which essentially clouds sight and can lead to blindness.|
|Location in Earth’s atmosphere||See Article History Alternative Title: In the stratosphere the temperature of the atmosphere rises with increasing height, a phenomenon created by the absorption of solar radiation by the ozone layer.|
Way up high in the Earth's atmospherecalled the stratosphere, there is a fairly high concentration of ozone molecules that are formed when the sun hits oxygen molecules. This part of the atmosphere is called the ozone layer. Ozone is formed in the atmosphere from oxygen molecules Why is the ozone layer important?
Ozone molecules in the atmosphere provide us with important protection from the rays of the sun. Specifically, these molecules are good at absorbing certain ultraviolet rays that can cause sunburn and skin cancer. How is the ozone layer getting damaged? It turns out that certain types of molecules can cause a chemical reaction when they come in contact with ozone molecules.
This causes the ozone to break up and become unable to absorb ultraviolet light. The main molecules that are destroying the ozone layer are called chlorofluorocarbons or CFCs. Chlorofluorocarbons CFCs Chlorofluorocarbons are a group of chemicals which are made up of only chlorinefluorinecarbonand hydrogen.
They were first used as refrigerants to keep things cold. A lot of people considered CFCs miracle chemicals. Eventually they were used in a variety of products including air conditioners, spray cans, fire extinguishers, and in manufacturing foams. Unfortunately, CFCs can eventually find their way into the Earth's atmosphere and the ozone layer.
Once they get there they destroy ozone molecules and cause the ozone layer to become depleted or thinner. CFCs became somewhat regulated, but it wasn't until that a treaty was formed called Montreal Protocol to try and stop the manufacture and use of CFCs throughout the world.
CFCs were to be banned and completely eliminated in developing countries by the year A hole in the ozone over the Antarctic Effects on Health Because CFCs last so long, the ozone layer will likely continue to thin for some time in the future.
This will cause an increase risk of sunburn and skin cancer. Skin cancer can be very dangerous. For this reason you should always wear sunscreen to protect your skin when you are outside in the sun for a long time.
Strong ultraviolet rays can also damage your eyes. You can protect them by wearing sunglasses. What can we do about it? There isn't much we can do about the CFCs that were released prior to the ban, but there are some things we can do: Old refrigerators - If you have a refrigerator made before it probably uses refrigerant made from CFCs.
Get a new refrigerator and be sure to have the old one disposed of properly.Ozone depletion describes two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.
Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3). Approximately 90 percent of the atmosphere’s ozone occurs in the stratosphere, the region.
At the time, CFCs were in wide use in refrigeration, air conditioning and aerosol spray cans. The compounds are inert and essentially nontoxic, characteristics that made them well-suited for these applications.
These same characteristics, however, also made them a danger to life on Earth. ozone layer depletion study guide by RadhikaReddy includes 77 questions covering vocabulary, terms and more.

In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.
