Question

The relative contribution of various green house gases to global warming is given in the following diagram:
Identify the green house gases.

• A. $A=C{O}_2;B=C{H}_4;C=N_{2}O;D=CFCs$
• B. $A=C{O}_2;B=CFCs;C=C{H}_4;D=N_{2}O$
• C. $A=CFCs;B=C{O}_2;C=C{H}_4;D=N_{2}O$
• D. $A=CFCs;B=C{H}_4;C=C{O}_2;D=N_{2}O$

Answer 1

The correct option is A $A=C{O}_2;B=C{H}_4;C=N_{2}O;D=CFCs$

Greenhouse gases are gases that absorb and emit radiation within the thermal infrared range. Carbon dioxide contributes mostly to global warming which is followed by methane, nitrous oxide and CFC.

So, the correct answer is option A.
