What is ultraviolet (UV) radiation?
Harmful radiation from the sun absorbed by the ozone layer.
What are Chlorofluorocarbons (CFCs)?

What is chlorine monoxide (ClO)?
A compound formed when chlorine steals an oxygen atom from ozone.
What is ozone depletion?
The thinning of the ozone layer due to human activities.
What are the effects of increased UV radiation?
Increased skin cancer, cataracts, damage to ecosystems, and harm to marine life.
What is the impact of CFCs on the ozone layer?
CFCs cause significant ozone depletion, leading to increased UV radiation reaching the Earth's surface.
What are the consequences of ozone depletion?
Increased UV radiation, leading to higher rates of skin cancer, cataracts, and damage to ecosystems.
What is the effect of ozone depletion?
Increased UV radiation reaches Earth, causing skin cancer and ecosystem damage.
What is the cause of ozone depletion?
The release of CFCs and other ozone-depleting substances.
What are the effects of increased UV radiation?
Increased skin cancer, cataracts, and damage to ecosystems.
What is the effect of CFCs on ozone molecules?
One CFC molecule can destroy thousands of ozone molecules.
