اوزون کی تہہ ہمیں سورج کے نقصان دہ _______ سے بچاتی ہے۔
-
A. Heat
-
B. Ultraviolet rays
-
C. Cold
-
D. None of these
Explanation
The stratospheric ozone layer is Earth's “sunscreen” protecting living things from too much ultraviolet radiation from the sun.
Oxygen layer in the atmosphere
Ozone protects us from the harmful ultraviolet radiation of the sun.
Ozone formula: O3
The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.
The ozone layer is depleting: Air pollution
اوزون کا عالمی دن _______ کو منایا جاتا ہے؟
-
A. June 5
-
B. April 4
-
C. October 24
-
D. September 16
Explanation
World Ozone Day also known as International Day for preservation of Ozone Layer is observed on 16 September
Proclaimed by United Nations General Assembly (in 1994)
Theme 2023:
Montreal Protocol: Fixing the Ozone Layer and Reducing Climate Change.
مندرجہ ذیل میں سے کون سی گیس بنیادی طور پر اوزون کی تہہ کی کمی کے لیے ذمہ دار ہے؟
-
A. Nitrogen oxide
-
B. CO2
-
C. Sulphur dioxide
-
D. Chlorofluorocarbon
Explanation
Chlorofluorocarbons (CFCs) release chlorine atoms in the atmosphere.These atoms break down ozone (O₃) molecules, causing depletion of the ozone layer.
