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.
13. Based on Figure 1, the average tropopause altitude for 30°N latitude would most likely be:
Your Answer is
Correct Answer is C
Explanation
Figure 1 shows that the average tropopause altitude points of 0° and 45°N correspond to altitudes of 17 km and 11 km respectively, so the average tropopause altitude of 30°N should be between the two, that is, 11 km-17 Between km
