Which one of the following is an example of an ozone-depleting substance mentioned in the text?
- Sulfur dioxide
- Carbon monoxide
- Nitrogen oxides
- Chlorofluorocarbons (CFCs) (correct)
What is the primary mechanism by which ozone-depleting substances damage the ozone layer according to the text?
What is the primary mechanism by which ozone-depleting substances damage the ozone layer according to the text?
- They catalyze the formation of ozone, leading to ozone depletion.
- They absorb UV radiation, preventing it from reaching the Earth's surface.
- They increase the destruction of ozone in a repetitive cycle. (correct)
- They increase the production of ozone in the stratosphere.
What is the primary effect of increased ultraviolet radiation reaching the Earth's surface according to the text?
What is the primary effect of increased ultraviolet radiation reaching the Earth's surface according to the text?
- It causes the ozone molecule to break apart, leading to a dynamic equilibrium.
- It damages human living tissues, increasing the incidence of cataracts, mutation during cell division, and skin cancer. (correct)
- It leads to the depletion of the ozone layer, allowing more ultraviolet radiation to reach the Earth.
- It increases the productivity of photosynthetic organisms, especially phytoplankton.
