Question

The gas which is the major contributor to globat warming is

• A. $NO_2$
• B. $N_2O$
• C. $SO_2$
• D. $O_2$
• E. $CO_2$

Answer 1

Answer: (E)

The gas which is the major contributor to global warming is carbon dioxide, represented as \( CO_2 \).

Carbon dioxide is released in large quantities due to the burning of fossil fuels, deforestation, and various industrial processes. It traps heat in the atmosphere, leading to the greenhouse effect and consequently to global warming.

• \( CO_2 \): Main greenhouse gas ✅
• \( NO_2 \): Contributes to pollution but is not the primary greenhouse gas
• \( SO_2 \): Causes acid rain, not a significant greenhouse gas
• \( O_2 \): Essential for life, not a greenhouse gas
• \( N_2O \): Potent greenhouse gas, but less abundant than \( CO_2 \)

Correct Answer: (E) \( CO_2 \)
