Understanding Ozone Depletion Effects

Front

What is the primary function of the stratospheric ozone layer?

Back

To protect the earth from ultraviolet radiation

Front

What does Ozone Depletion Potential (ODP) measure? Options: The ability of a substance to absorb ultraviolet radiation, The ability of a substance to destroy ozone in the stratosphere, The ability of a substance to increase greenhouse gas emissions, The ability of a substance to dissolve in water

Back

The ability of a substance to destroy ozone in the stratosphere

Front

Which health issue is linked to the thinning of the stratospheric ozone layer?

Back

Increased rates of skin cancer

Front

What is the chemical formula for ozone?

Back

Front

Which element in CFCs and HCFCs is responsible for ozone depletion?

Back

Chlorine

Front

How long can a single chlorine atom last in the stratosphere, destroying ozone molecules?

Back

120 years

Front

What is the environmental impact of stratospheric ozone depletion on agriculture?

Back

Decreased crop yields

Front

Which of the following statements is true about HFCs? Options: They contain chlorine that affects the ozone layer, They have a high Global Warming Potential (GWP), They are made up of Hydrogen, Chlorine, and Carbon, They dissolve in water easily

Back

They have a high Global Warming Potential (GWP)

Front

What evidence suggests that chlorine-containing refrigerants are responsible for ozone depletion? Options: The rise in chlorine matches the rise in volcanic activity, The rise in chlorine matches the rise in CFC and HCFC emissions, The rise in chlorine matches the rise in natural sources of chlorine, The rise in chlorine matches the rise in water vapor

Back

The rise in chlorine matches the rise in CFC and HCFC emissions

Front

What happens when a chlorine atom encounters an ozone molecule?

Back

It forms chlorine monoxide (ClO) and leaves an oxygen molecule (O_2) behind.
