Chapter 13 Lesson 3
Earth’s weather occurs in the troposphere, and air pressure is an important factor in
weather. Use the data on air pressure in the table to make a graph (on graph paper) showing how
air pressure changes as you move upward in the troposphere. Answer the questions.

1. Describe the relationship between altitude and air pressure shown in the graph.
2. Estimate the average air pressure in a hole 500 meters below sea level.
3. If you were flying in a plane at an altitude of 1,500 meters, what would the air pressure outside the plane
be?
When you fly that high, why might your ears “pop”?
