Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Atmospheric Layers
The atmosphere is divided into distinct layers based on temperature gradients and composition. The primary layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics, such as temperature changes with altitude and the presence of specific gases, which influence weather patterns and climate.

Temperature Gradient
The temperature gradient refers to the change in temperature with altitude in the atmosphere. In the troposphere, temperature decreases with height, while in the stratosphere, it increases due to the absorption of ultraviolet radiation by ozone. This gradient is crucial for understanding atmospheric stability and the behavior of weather systems.

Composition of the Atmosphere
The composition of the atmosphere varies with altitude, affecting its physical and chemical properties. The lower atmosphere contains a higher concentration of water vapor and pollutants, while the upper layers have less density and different gas compositions. This variation plays a significant role in atmospheric dynamics and the formation of different weather phenomena.

Textbook Question
Air pollution in the Mexico City metropolitan area is among the worst in the world. The concentration of ozone in Mexico City has been measured at 441 ppb (0.441 ppm). Mexico City sits at an altitude of 7400 feet, which means its atmospheric pressure is only 0.67 atm. (a) Calculate the partial pressure of ozone at 441 ppb if the atmospheric pressure is 0.67 atm.
