Real questions that test this
कोणत्या वायूमुळे मुख्यत्वे ओझोन थराचा हास होतो ? / The main gas responsible for ozone depletion is :
1)कार्बन डाय ऑक्साईड / Carbon dioxide
2)नायट्रोजन डाय ऑक्साईड / Nitrogen dioxide
3)मिथेन / Methane
4)क्लोरो फल्यूरो कार्बन / Chloro fluro carbon✓ Correct
Chlorofluorocarbons (CFCs) release chlorine atoms upon UV exposure, which actively break down ozone molecules in the stratosphere, causing depletion.
