Arrange the following greenhouse gases in the increasing order of their life time in the earth's atmosphere:
A. SF6 (Sulfur Hexafluoride)
B. N2O (Nitrous Oxide)
C. H2O vapor (Water Vapor)
D. CH4 (Methane)
Choose the correct answer from the options given below:
- A.
C, D, B, A
- B.
C, D, A, B
- C.
A, B, C, D
- D.
B, A, D, C
Attempted by 13 students.
Show answer & explanation
Correct answer: A
The atmospheric lifetime of a greenhouse gas determines how long it remains in the atmosphere. Water vapor (C) has the shortest lifetime, lasting only days. Methane (D) persists for about a decade. Nitrous oxide (B) remains for over a century. Sulfur hexafluoride (A) has the longest lifetime, lasting thousands of years. Therefore, the increasing order of life time is C, D, B, A.
