Question

As we go to higher altitudes, what happens to the temperature?

• A. It increases
• B. It decreases
• C. It remains constant
• D. It first increases and then decreases

Answer 1

The correct option is B It decreases

As we increase elevation, there is less air above us thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
