Which atmospheric layer lies above the Stratosphere?

Which atmospheric layer lies above the Stratosphere?

• A. Mesosphere
• B. Troposphere
• C. Thermosphere
• D. Exosphere

Answer: (A)

Understanding how Earth's atmosphere is layered helps here. The Stratosphere sits above the Troposphere and below the Mesosphere. In the Stratosphere, temperature increases with altitude due to ozone absorbing ultraviolet radiation, up to the stratopause. Above that boundary lies the Mesosphere, where temperature decreases with height, making it cooler as you go higher. The Mesopause marks the top of this layer, and above it is the Thermosphere, followed by the Exosphere. So, the layer directly above the Stratosphere is the Mesosphere.
