Ozone is formed by the reaction between ultraviolet rays of the sun and atmospheric oxygen. The ultraviolet rays break 1 molecule of into 2 oxygen atoms. These 2 atoms are highly reactive and each atom combines with another molecule of oxygen to form ozone molecule.
Why is the stratospheric ozone good?
Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. … Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
What produces good ozone?
Stratospheric “good” ozone
Ozone is created when the kind of oxygen we breathe—O2—is split apart by sunlight into single oxygen atoms. Single oxygen atoms can re-join to make O2, or they can join with O2 molecules to make ozone (O3).
Why is ozone bad for you?
How is Ozone Harmful? … When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
Where is the bad ozone located?
“Bad” ozone is found in the troposphere, the layer nearest the ground. Tropospheric ozone is a harmful pollutant which forms when sunlight alters various chemicals emitted by humans. “Good” ozone forms in the stratosphere, the next higher layer where some jet planes fly.
What is a bad ozone?
Ozone occurs in two layers of the atmosphere. … Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. It is a main ingredient of urban smog.
What is an unhealthy ozone level?
Good (0-50) No health impacts are expected when air quality is in this range. Moderate (51-100) Unusually sensitive people should consider limiting prolonged outdoor exertion. Unhealthy for. Sensitive Groups. (101-150)
How can you tell if you are being affected by ozone?
People exposed to elevated levels of ozone may experience a variety of symptoms. The most common symptom is a feeling of irritation in the eyes, nose and throat. Some people may also experience respiratory or heart symptoms such as shortness of breath, chest pain, and wheezing.
How ozone is created?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.
Why is ozone important?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals.
What are the two types of ozone?
Ozone or “O3” is a colorless gas composed of three atoms of oxygen (O3). There are two types of ozone, both “good” ozone and “bad” ozone.
How can ozone be both good and bad quizlet?
What is the difference between “good” and “bad” ozone? Good ozone is found in the stratosphere and good ozone is decreasing in our protective ozone layer. Bad ozone is found in the trospheric, bad ozone increasing in the air we breathe.
How does good and bad ozone form quizlet?
Terms in this set (11) how is “good” ozone formed? … stratospheric clouds form during the winter, but then the sun comes out in the spring and uv rays break through the clouds, CFCs in the atmosphere react with sunlight and deplete the ozone layer.
What is ozone made up of quizlet?
Essentially, ozone (O3) is an unstable and highly reactive form of oxygen. The ozone molecule is made up of three oxygen atoms that are bound together, whereas the oxygen we breathe (O2) contains only two oxygen atoms.
Can you smell ozone?
Ozone has a distinctive smell that humans can detect even in small concentrations — as few as 10 parts per billion. Here are some of the ways the smell of ozone is described: Metallic. Like a burning wire.
Can you recover from ozone exposure?
The effects are reversible, with improvement and recovery to baseline varying from a few hours to 48 hours after an elevated ozone exposure.
What is a good ozone level?
Good (0-50) It’s a great day to be active outside. Moderate (51-100) Some people who may be un- usually sensitive to ozone. Unusually sensitive people: Consider reducing prolonged or heavy outdoor exertion. Watch for symptoms such as coughing or shortness of breath.
How ozone is both beneficial and damaging?
1. Ozone layer which is present in the stratosphere is only beneficial as it protects us from the direct ultraviolet rays coming from the sun. … The ozone layer absorbs the UV rays from the sunlight and hence protects the humans as well as other living beings from radiation health effects.
What is the problem with ozone?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
How is ozone good and bad?
In the stratosphere, which extends from about 10 to 50 km above the Earth’s surface, ozone is ‘good’ as it protects life on Earth from the sun’s ultraviolet rays. … Too much of this ground-level ozone is ‘bad’ as it is harmful to breathe and also damages vegetation.
How long does ozone last?
According to the Home Air Advisor, ozone lasts between 30 minutes and 4 hours before it converts back into oxygen. Higher levels of ozone concentration generally take 3 to 4 hours to dissipate, while lower levels can clear out in about 2 hours.
Will breathing ozone hurt you?
People who buy ozone generators may not be aware that ozone can harm the cells in the lungs and respiratory airways. Exposure to ozone irritates and inflames the lining of the respiratory system. This causes symptoms including coughing, chest tightness, shortness of breath, and impaired breathing.
Is O3 flammable?
No. Ozone, by definition, cannot be flammable. For a substance to be flammable, it needs to burn. It needs to be a fuel and not an oxidizer in the fire reaction.
