how do chlorofluorocarbons contribute to ozone depletion

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

How do CFCs cause ozone depletion?

Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

How do chlorofluorocarbons contribute to ozone depletion Brainly?

a. chlorine atom (Cl) breaks apart the ozone molecule. ... CFCs build up and block the filtering effects of the ozone layer.

How do CFCs cause ozone depletion quizlet?

How do CFCs cause ozone depletion? Ultraviolet radiation breaks down CFCs, molecules containing chlorine. Chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. What would happen to the oxygen atoms in ozone if the ozone layer were completely destroyed by ultraviolet radiation?

How does CFCs affect the thickness of ozone layer?

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.

What are 3 causes of depletion to 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).

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 is good stratospheric ozone formed?

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.

What of the following is a health risk associated with ground level ozone?

Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs. Repeated exposure may permanently scar lung tissue.

How does the ozone layer affect life on Earth?

The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. ... The ozone layer filters out most of the sun's harmful UV radiation and is therefore crucial to life on Earth.

Do chlorofluorocarbons destroy ozone layer?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

What is causing the problem of ozone depletion 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 is ozone and why is ozone important to life on Earth?

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.
