Paper 1 · People, Development and Environment
The rank of greenhouse gas emissions at the global level, in decreasing order, is
ACarbon dioxide, Methane, Sulphur dioxide and Fluorinated gases
BFluorinated gases, Carbon dioxide, Nitrous oxide, Methane
CCarbon dioxide, Methane, Nitrous oxide and Fluorinated gases ✓ Correct
DMethane, Nitrous oxide, Carbon dioxide and Fluorinated gases
Correct answer: (C) Carbon dioxide, Methane, Nitrous oxide and Fluorinated gases — In decreasing order it is carbon dioxide, methane, nitrous oxide and fluorinated gases, so that is the answer.
Explanation
★In decreasing order it is carbon dioxide, methane, nitrous oxide and fluorinated gases, so that is the answer.
★Carbon dioxide is by far the largest greenhouse gas emission.
★Methane comes next, then nitrous oxide.
★Fluorinated gases make up the smallest share.
★So the decreasing order is carbon dioxide, methane, nitrous oxide, fluorinated gases.
★So the answer is carbon dioxide, methane, nitrous oxide and fluorinated gases.
