What are 3 facts about the ozone layer?

The ozone layer, our Earth’s sunscreen, absorbs about 98 percent of this devastating UV light. The ozone layer is getting thinner. Chemicals called chlorofluorocarbons (CFCs) are a reason we have a thinning ozone layer. A chlorofluorocarbon (CFC) is a molecule that contains the elements carbon, chlorine, and fluorine.

What are the functions of ozone layer?

The ozone layer protects the Earth against most UVB coming from the sun. It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen. However, these precautions will become more important as ozone depletion worsens.

What are the characteristics atmosphere?

Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

What are the factors of ozone layer?

The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons).

What are the advantages of ozone layer?

The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun. In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn.

What is the function of ozone in the environment?

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.

What is effects of ozone layer?

Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems. Too much exposure to UV is believed to be contributing to the increase in melanoma, the most fatal of all skin cancers.

Who discovered ozone layer?

The Ozone Layer was discovered by the French physicists Charles Fabry and Henri Buisson in 1913. Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun.

Where is ozone layer located?

Ozone location.

Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth’s surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer” (see Figure Q1-2).

What is the function of ozone layer Class 3?

The function of the ozone (O3) layer in the upper atmosphere is to prevent harmful ultraviolet (UV) rays from reaching the Earth’s surface, as these UV rays cause various types of diseases including skin cancer.

What is the function of the ozone layer Quizizz?

What is an important role of the Ozone Layer? It protects the mesosphere from the Sun’s harmful rays. It protects the troposphere from the Sun’s harmful rays. It prevents floods, hurricanes, and other storms.

What is ozone layer Class 9?

What is the Ozone Layer? The ozone layer is the layer present in the Stratosphere. It absorbs the harmful ultraviolet rays that come from the sun. Moreover, it causes harmful radiation that has a high concentration of ozone (O3) which is harmful to living beings on the earth.

What is the importance of ozone depletion?

Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.

How many oxygen atoms does a molecule of ozone contain?

three oxygen atoms
Ozone (O3) is a triatomic, molecule, consisting of three oxygen atoms. Ozone in the upper atmosphere protects living organisms by preventing damaging ultraviolet light from reaching the Earth’s surface. O3 is the formula for ozone. It has three oxygen atoms.

Which of the following represents ozone gas molecule?

The correct answer is O3. Ozone is formed in the atmosphere by the combination of atomic oxygen with an oxygen molecule.

What are the advantages and disadvantages of ozone layer?

Advantage of Ozone–When it is in the stratosphere it does not allow the ultraviolet radiations to reach the earth as UV radiations cause skin cancer and cataract. Disadvantage of ozone: On ground level ozone is poisonous gas.

How we can protect ozone layer?

Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process. Some of the most dangerous gases are CFCs (chlorofluorocarbons), halogenated hydrocarbon, methyl bromide and nitrous oxide. Minimize the use of cars. The best transport option is urban, bicycle, or walking.

What are the two types of ozone?

What is “Good” Versus “Bad” Ozone? Ozone is either considered “good” or “bad”, depending on where it occurs. “Good” ozone is also known as stratospheric and “bad” ozone is more commonly known as ground-level.
