What happens to temperature in the stratosphere as altitude increases?

In the stratosphere, as altitude increases, the temperature actually increases. This phenomenon occurs due to the presence of the ozone layer, which absorbs ultraviolet (UV) radiation from the sun. As UV radiation is absorbed, it warms the stratosphere. In contrast to the troposphere, where temperature typically decreases with altitude, the stratosphere exhibits this peculiar increase in temperature.

This temperature profile is important for understanding various atmospheric phenomena, including the stability of the stratosphere, which allows for the existence of jet streams and influences weather patterns. The other choices do not accurately reflect the behavior of temperature with altitude in the stratosphere. Thus, acknowledging that temperature increases with altitude in this atmospheric layer is crucial for grasping basic atmospheric science concepts.
