Passage VI
Earth's atmosphere consists of various gases and suspended liquid and solid matter. The atmosphere can be divided into layers based on air temperature and/or composition. Figure 1 shows the layers of the atmosphere, the altitude of the layer boundaries, in kilometers (km), and the air pressure, in millibars (mb), at those boundaries. Figure 2 shows the average air temperature, in degrees Celsius (°C), in arctic (cold) and tropical (warm) air masses at various altitudes. Table 1 shows air pressure and temperature readings from weather instruments carried into the stratosphere by balloons on 2 separate days.
32. According to Figure 1, several atmospheric layers overlap one another. Which of the following describes atmospheric layers that share part of a common altitude range?
Your Answer is
Correct Answer is J
Explanation
Look at figure 1, mesosphere and chemosphere do share a height range of 50-80 km
