Ozone is formed in the stratosphere by the reaction of ultraviolet radiation striking an oxygen molecule. This results in the oxygen molecule splitting apart and forming atomic oxygen (O2 + hv = O + O). Atomic oxygen can now react with molecular oxygen to form ozone (O+O2 = O3).

Accordingly, how is ozone produced quizlet?

Created when UV lights split oxygen molecules (O2) into single oxygen atoms. Single oxygen atoms join other oxygen molecules to form triplets of oxygen atoms, or ozone molecules (O3). Ozone is continually being created and destroyed with UV light being absorbed in this process.

Additionally, what is the purpose of the ozone layer quizlet? To stop excessive amounts of ultraviolet radiation reaching the Earth's surface. It absorbs the UV rays to prevent them from reaching the ground.

Considering this, what causes the ozone hole quizlet?

Ozone depletion occurs when chlorofluorocarbons (CFCs)—formerly found in aerosol spray cans and refrigerants—are released into the atmosphere. Depletion of the ozone layer has consequences on humans, animals and plants. What can I do to save the Ozone Layer?

What does the ozone layer absorb quizlet?

The ozone layer absorbs most of the ultraviolet light from the sun. UV light is harmful to organisms because it can damage the genetic material in living cells. By shielding the Earth's surface from most of the sub's ultraviolet light, the ozone in the stratosphere acts like a sunscreen for the Earth's inhabitants.

What is the difference between good ozone and bad ozone quizlet?

Describe the difference between good and bad ozone. Good ozone is in the stratosphere and protects the earth from harmful ultraviolet radiation. Bad ozone is in the troposphere and is a pollutant. global warming is a process caused the atmospheric absorption of infrared heat energy radiated from the earth's surface.

How is good stratospheric ozone formed?

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis.

What do u mean by ozone layer?

The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun.

What is an ozone depleting substance?

Ozone depleting substances are man-made gases that destroy ozone once they reach the ozone layer. Ozone depleting substances include: chlorofluorocarbons (CFCs) hydrochlorofluorocarbons (HCFCs)

What is an ozone generator?

Ozone generators intentionally produce the toxic gas ozone and are sold as air cleaners for commercial and residential applications. Specifically, they are advertised to deodorize, disinfect, kill or remove dangerous or irritating airborne particles in indoor environments.

Where are chlorofluorocarbons found?

Chlorofluorocarbons (CFCs) are anthropogenic compounds that have been released into the atmosphere since the 1930s in various applications such as in air-conditioning, refrigeration, blowing agents in foams, insulations and packing materials, propellants in aerosol cans, and as solvents.

Where does ozone creation occur quizlet?

Ozone is formed in the stratosphere by the reaction of ultraviolet radiation striking an oxygen molecule. This results in the oxygen molecule splitting apart and forming atomic oxygen (O2 + hv = O + O). Atomic oxygen can now react with molecular oxygen to form ozone (O+O2 = O3).

How does the ozone layer affect life on Earth?

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface.

What is the major cause of ozone depletion?

Man-made causes of depletion of ozone layer: The main cause for the depletion of ozone is determined as excessive release of chlorine and bromine from man-made compounds such as chlorofluorocarbons (CFCs). The emission of ODS account for roughly 90% of total depletion of ozone layer in stratosphere.

Why is there a hole in the 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), referred to as ozone-depleting substances (ODS).

How do chlorofluorocarbons affect Earth's ozone layer quizlet?

Ozone Depletion Ozone is destroyed by chlorofluorocarbons (CFC's). CFC's breakdown and release chlorine atoms which combine with O3 and break them down to O2. , CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing the chlorine that catalytically destroys ozone.

Who discovered the ozone hole?

In spring, temperatures begin to rise, the ice evaporates, and the ozone layer starts to recover. In 1984 British Antarctic Survey scientists, Joesph Farman , Brian Gardiner, and Jonathan Shanklin, discovered a recurring springtime Antarctic ozone hole .

How does ozone depletion impact human health?

Depletion of the ozone layer has consequences on humans, animals, and plants. This typically results from higher UV levels reaching us on earth. Research confirms that high levels of UV Rays cause non-melanoma skin cancer. Additionally, it plays a major role in malignant melanoma development.

What effects can stratospheric ozone depletion have on the environment?

The thinning is most pronounced in the polar regions, especially over Antarctica. 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 do chlorofluorocarbons contribute to ozone depletion?

Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. The seasons have an impact on the Antarctic ozone hole. When sunlight returns in the spring, the chlorine begins to destroy ozone.

Where is ozone formed and stored?

Ozone is produced in the high stratosphere, stored in the lower stratosphere, and destroyed in the troposphere.
