Correct option is C
The
"Ozone Hole" refers to the
thinning or depletion of the ozone layer in the
stratosphere, particularly over
Antarctica. It is not an actual "hole" but rather a
region where the ozone concentration is significantly reduced due to chemical reactions.
Key Causes of Ozone Depletion:
·
Chlorofluorocarbons (CFCs) – Released from refrigerants, air conditioners, and aerosol sprays.
·
Halons & Bromine Compounds – Found in fire extinguishers and industrial processes.
·
Nitrogen Oxides (NOx) – Emitted from aircraft, industries, and fertilizers.
·
Extreme Cold Conditions in Antarctica – Triggers chemical reactions leading to ozone breakdown.
·
Sunlight Activation – UV rays break down CFCs, releasing
chlorine (Cl) atoms that destroy ozone (O3).
