The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. Ozone is formed naturally when oxygen in the Earth's atmosphere is exposed to strong concentrations of ultraviolet light. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. Each of those oxygen atoms then binds with an oxygen molecule to form an ozone molecule. In order from lowest to highest, they are the Troposphere, the Ozone Layer, and the Stratosphere. But we would be ill served to forget the Ozone Layer. Weird & WackyWe use cookies to personalise content and ads, to provide social media features and to analyse our traffic. It is a pale blue gas with a distinctively pungent smell. It contains a high concentration of ozone(O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. There are many features of our world that make the planet especially well suited to life on Earth. Then, when those oxygen atoms come into contact with oxygen gas, they join to become ozone. Here, we will discuss the nature of the Ozone Layer, why it is so important, and what we can do to preserve it.Earth’s atmosphere is made up of several layers. Thus, in the third stage of the cycle, the ozone gas then breaks into one oxygen gas molecule and an oxygen atom, hence absorbing much of the remaining UV light. Ozone , or trioxygen, is an inorganic molecule with the chemical formula O 3. The ozone layer effectively blocks almost all solar radiation of wavelengths less than 290 nanometres from reaching Earth’s surface, including certain types of ultraviolet (UV) and other forms of radiation that could injure or kill most living things. 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. The first stage of this cycle occurs when short-wavelength UV light from the sun hits a molecule of oxygen gas. Then, when those oxygen atoms come into contact with oxygen gas, they join to become ozone.Even though our atmosphere can heal the ozone layer, CFCs and many other chemicals we use are highly destructive to ozone. You consent to our cookies if you continue to use our website. Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. In the rarified air at altitude, some of the oxygen molecules drift upwards while others combine with unsplit O2 to …

Originally Answered: How did the ozone layer form? Exposure to UV light can lead to skin cancer and cataracts, and can damage the body's immune system [source: EPA]. We are very fortunate to live on a planet that can replenish our ozone layer, otherwise, the damage done years ago would have been permanent.

It’s pretty scary when you think about it. This magnificent feature of our atmosphere is as necessary for life on Earth as it is strange and wonderful.

Ozone is created in the stratosphere when ultraviolet light from the sun splits an oxygen molecule into two singleoxygen atoms. The light has so much energy that it breaks the oxygen bond holding the atoms together, thus creating two oxygen In the second stage, each of the two remaining oxygen atoms will then latch onto two oxygen gas molecules, creating two separate ozone molecules [source: Short-wavelength UV light has enough energy to break apart ozone molecules (which are more volatile and easier to separate than oxygen molecules). Here are a few more interesting facts about ozone that you may not be aware of. It also forms artificially when nitrogen and oxygen emissions from internal combustion engines are exposed to sunlight. The ozone layer forms continuously as ionizing radiation from the sun hits O2 molecules in the upper atmosphere and breaked then apart. It is a very common substance that can be readily made via natural processes. The ozone layer is mainly found in the lower portion of the stratosphere, fro…

If we do not limit CFC use, we could damage the ozone layer again. The ground-level troposphere is produced when carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs) react to sunlight. This is why it is so important that we protect our precious ozone layer.You may have heard that an enormous hole in the ozone layer had once formed in the atmosphere. For years, Fortunately, people did reduce CFC emissions- and through natural processes- the hole in the ozone was able to reform itself. When UV light hits oxygen gas, it breaks it down to two oxygen atoms. The area where we live is often called the biosphere because that is where most living things exist- but speaking in atmospheric terms, it is really intermingled with the Some people believe the word ‘ozone’ refers to the location of the ozone layer because it contains the word ‘zone.’ But ozone refers to the predominant chemical that makes up the ozone layer. We still need to be careful, however. Ozone is a lighter than air molecule that is made up of three oxygen atoms.

Think about a time when you or someone you know spent too much time out in the sun and got a sunburn. This is why we need the ozone layer. This would lead to higher temperatures, and higher rates of skin cancer all over the world.The UV light that the ozone layer protects us from is a necessary component in the creation of ozone molecules. The UV light that the ozone layer protects us from is a necessary component in the creation of ozone molecules. Now think about the fact that those burns are just 3% of what they would have been if there was no ozone layer to filter out most of the UV rays. When it comes to UV light, what we don't know (or don't see) can hurt us. Without a healthy ozone layer, life on Earth would be very different.One of the strangest things about UV radiation is that it can burn your skin even if you do not feel hot.
