Question

Arrange the following layers of atmosphere starting from earth's surface.
A. Troposphere
B. Stratosphere
C. Tropopause
D. Stratopause
E. Mesosphere

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

Hint:

A mnemonic for the layers is "Trust Me in The Exam": Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere. The 'pauses' are the ceilings of the layers below them (e.g., Tropopause is the top of the Troposphere).

Answer 1

The Correct Option is C

Step 1: Recognize the primary atmospheric layers. The atmosphere is structured into layers defined by temperature changes. From the surface upwards, these layers are the Troposphere, Stratosphere, Mesosphere, and Thermosphere.

Step 2: Identify the boundary regions (the 'pauses'). The 'pauses' delineate the main layers. The tropopause sits between the troposphere and stratosphere. The stratopause separates the stratosphere and mesosphere.

Step 3: Establish the sequence ascending from the Earth's surface.

1. Troposphere (A): The lowest layer, the location of weather and where we reside.
2. Tropopause (C): The upper boundary of the troposphere.
3. Stratosphere (B): The layer above the troposphere, including the ozone layer.
4. Stratopause (D): The upper boundary of the stratosphere.
5. Mesosphere (E): The layer above the stratosphere.

Conclusion: The correct order from the surface up is A, C, B, D, E.
