Options for question 33

Show the answer and explanation
CorrectNot quiteAnswer B

Correct answer: B

Explanation

  1. Water vapour is present in far larger amounts than any other greenhouse gas and causes most of the natural greenhouse effect.

  2. Its amount follows the temperature, so it amplifies warming caused by carbon dioxide rather than starting it.

Worth noting

Carbon dioxide is the main greenhouse gas added by human activity, which is a different question.
