Passage III
The tropopause is the transition between 2 layers of Earth's s atmosphere: the troposphere (the layer that begins at Earth's surface) and the stratosphere (the layer just above the troposphere). Figure 1 shows how air temperature changes with altitude at 3 latitudes (0°, 45° N, and 90° N), as well as the average tropopause altitude for each of those latitudes. Figure 2 shows, for the tropical latitudes, the monthly averages for tropopause altitude, tropopause air pressure, and tropopause air temperature determined for a particular 30-year perIod.
12. According to Figure 1, the air temperature at 0° latitude is the same as the air temperature at 45°N latitude at an altitude closest to which of the following?
Your Answer is
Correct Answer is G
Explanation
The stem of the question says that the air temperature at 45°N and 0° is the same, so look at the intersection point of the two lines in figure 1, the vertical coordinate altitude of the intersection point is about 13 km
