Describe how air pressure changes with an increase in altitude. Does it change at a constant rate?

Does air pressure increase or decrease with an increase in altitude? Is the rate of change constant or variable? Explain.

What is the environmental lapse rate, and how is it determined?

What are the major components of clean, dry air? List two significant variable components.

Explain how past temperatures are determined using oxygen-isotope analysis.

Refer to the graph in the earlier figures to answer the following:

a. Approximately how much does the air pressure drop (in millibars) between the surface and 4 kilometers? (Use a surface pressure of 1000 millibars.)

b. How much does the pressure drop between 4 and 8 kilometers?

c. Based on your answers to parts a and b, answer the following: With an increase in altitude, air pressure decreases at a(n) (constant, increasing, decreasing) rate. Underline the correct answer.

What are proxy data, and why are they necessary in the study of climate change?

Why are temperatures in the thermosphere not strictly comparable to those experienced near Earth’s surface?
