What phenomena would you observe when moving from the troposphere to the stratosphere?

When moving from the troposphere to the stratosphere, the most notable phenomenon is an increase in temperature. This is due to the presence of the ozone layer in the stratosphere, which absorbs ultraviolet radiation from the Sun, causing a rise in temperature as you ascend through this layer of the atmosphere.

In the troposphere, temperature generally decreases with altitude, leading to cooler conditions as one goes higher. However, this trend reverses in the stratosphere, where the absorption of UV radiation leads to warmer temperatures. This increase in temperature at higher altitudes is a key distinguishing feature of the stratosphere as compared to the layer directly below it.

Choices related to atmospheric pressure and weather disturbances do not accurately reflect the transition from the troposphere to the stratosphere in the same manner. While atmospheric pressure does indeed decrease with altitude in both layers, the correct focus is on temperature as a primary observation during this transition.
