Low ozone concentrations in the atmosphere are primarily caused by human activities such as the release of ozone-depleting substances like chlorofluorocarbons (CFCs) and other pollutants. These substances break down ozone molecules in the stratosphere, leading to a decrease in ozone levels.
What else can I help you with?
What molecule is made up of three atoms of oxygen?
You must be thinking of ozone or trioxygen (O3). It is a triatomic molecule, consisting of three oxygen atoms. It is an allotrope of oxygen that is much less stable than the diatomic O2. Ground-level ozone is an air pollutant with harmful effects on the respiratory systems of animals. The ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth's surface. It is present in low concentrations throughout the Earth's atmosphere.
Is there oxygen on Mars' atmosphere?
Yes, there is oxygen in the atmosphere of Mars, but it is present in very low concentrations, about 0.13%. This is much lower compared to Earth's atmosphere, which is around 21% oxygen.
What is the percent composition of Chlorofluorocarbons in the atmosphere?
Chlorofluorocarbons (CFCs) are present in very low concentrations in the Earth's atmosphere, typically measured in parts per trillion (ppt) or parts per quadrillion (ppq). The percent composition of CFCs in the atmosphere is extremely low, usually less than 1 part per trillion.
How do you make an ozone hole?
An ozone hole is formed when the amount of ozone in the upper atmosphere gets depleted to dangerously low levels. Normally, Chlorofluorocarbons, or CFC's, are responsible for this. In sunlight, CFC's form chlorine radicals which react with Ozone to produce Oxygen gas. If XCl is a CFC, the steps in which reactions proceed are: In sunlight in the upper atmosphere: XCl ------> X + Cl Cl is the chlorine radical, which is extremely reactive. Cl + O3 -----> O2 + ClO ClO is another radical, which is also extremely reactive. ClO + O3 -----> Cl + 2O2 As you can see, the Chlorine radical, Cl, is produced again at the last step, allowing it to repeat the steps again and again. In fact, it is estimated that each Chlorine atom can react with up to 200,000 ozone molecules, before decaying.
Can you smell ammonia?
Yes, ammonia has a strong, pungent odor that can be detected at low concentrations in the air.
What causes low ozone concentrations in the atmosphere?
Low ozone concentrations are caused in part by chlorofluorocarbons, or CFCs.
What penetrates the atmosphere when the ozone layer gets thinner?
When the ozone layer gets thinner, its power becomes low. It causes the UV to penetrate it.
Is it more desirable to have a small ozone hole and high concentrations of ozone or to have large ozone hole and low concentrations of ozone?
It is desirable to have small ozone hole. Because UV can't penetrate normal ozone blanket too.
How ozone is formed in the lower atmosphere?
Ozone as we know in low atmosphere is harmful. It is formed by thunder and lightening.
Does lightning destroy the ozone?
no, it is too low in the atmosphere.
What is ozone's proportion in air?
Ozone's proportion is very low in the atmosphere. It is a rare gas.
If ozone is poisonous why is the ozone emitted during baking bread not considered dangerous?
The ozone produced during baking bread is typically in very low concentrations and is not emitted in harmful amounts. Ozone can be harmful at high concentrations, such as in air pollution, but in the case of baking bread, the levels are too low to pose a risk to human health.
Where are the holes of ozone layer?
There are holes over the poles. These holes are lowered concentrations.
What happens when ozone drops too low and meets gases lower in the atmosphere?
Ozone in the ozone layer will never get into the lower atmosphere. Ozone that is created at the surface can interact with sunlight and other pollutants to create smog.

What color represents the ozone hole over Antarctica?
Color assignments on maps of concentrations of any constituent are arbitrary, and provided as a key on the map. There is no "natural" means of providing such a representative color. On the maps provided by the US-NASA, high ozone concentrations are yellow or white, and low concentrations are depected as dark blue, with intermediate values usually in red. So on US-NASA maps, the ozone hole is usually shown as a red circle with a blue center, when it is winter at that pole. See the link below.
