Question

The boundary between the troposphere and stratosphere is known as the

• A. Tropopause
• B. Stratopause
• C. Mesopause
• D. Thermopause

Hint:

• Atmospheric layers from bottom to top: Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
• The suffix "-pause" generally denotes the boundary at the top of a layer.
• Troposphere $\rightarrow$ Tropopause (boundary)
• Stratosphere $\rightarrow$ Stratopause (boundary)
• Mesosphere $\rightarrow$ Mesopause (boundary)
• Thermosphere $\rightarrow$ Thermopause (boundary, also called Exobase)

Answer 1

The Correct Option is A

The boundary between the troposphere and stratosphere is referred to as the Tropopause. In the Earth's atmosphere, the tropopause serves as a transition layer between these two significant atmospheric regions.

• Troposphere: The lowest part of the Earth's atmosphere where weather phenomena occur and temperature generally decreases with altitude.
• Stratosphere: Located above the troposphere, characterized by a temperature inversion or increase in temperature with altitude, and contains the ozone layer.

The correct option for this boundary is the Tropopause, marking a shift from the temperature-decreasing troposphere to the temperature-increasing stratosphere.
