Question

Arrange the atmospheric layers starting from the Earth’s surface upwards:
(A) Mesosphere
(B) Stratosphere
(C) Stratopause
(D) Mesopause
(E) Troposphere
Choose the correct answer from the options given below:

• A. (E), (C), (B), (D), (A)
• B. (E), (C), (B), (A), (D)
• C. (E), (B), (C), (A), (D)
• D. (E), (B), (C), (D), (A)

Answer 1

The Correct Option is C

The Earth’s atmosphere is divided into several layers, each with distinct properties and temperature gradients. The layers are typically arranged in ascending order from the Earth’s surface as follows:

1. Troposphere: Closest to Earth's surface; weather phenomena occur here.
2. Stratosphere: Above the troposphere; contains the ozone layer.
3. Mesosphere: Above the stratosphere; meteors burn up here.

Additionally, two boundaries separate these layers:

• Stratopause: The boundary between the stratosphere and the mesosphere.
• Mesopause: The boundary marking the top of the mesosphere.

Arranging the given atmospheric layers starting from the Earth's surface:

1. (E) Troposphere
2. (B) Stratosphere
3. (C) Stratopause
4. (A) Mesosphere
5. (D) Mesopause

The correct sequence is: (E), (B), (C), (A), (D).

Answer 2

The correct arrangement of atmospheric layers from Earth's surface upwards is (E), (B), (C), (A), (D).

Additional Context:

• Atmospheric Structure:
  1. Troposphere (E): 0-12 km (weather occurs here)
  2. Stratosphere (B): 12-50 km (contains ozone layer)
  3. Stratopause (C): Boundary at ~50 km
  4. Mesosphere (A): 50-85 km (meteors burn here)
  5. Mesopause (D): Boundary at ~85 km (coldest atmospheric point)
• Key Features:
  • Temperature inversion at stratosphere due to ozone absorption
  • Mesosphere temperatures drop to -90°C
• Practical Relevance:
  • Commercial flights in upper troposphere
  • Satellites orbit above mesopause

Correct Answer: (3) (E), (B), (C), (A), (D).
