The height at which atmospheric pressure declines by a factor of e (an irrational number equal to 2.71828) is called __________.
Correct answer: B. Scale height (H)
- A. Average height (H)
- B. Scale height (H)
- C. Mean height (H)
- D. Standard height (H)
Explanation
The scale height is the vertical distance over which atmospheric pressure falls to 1/e, or about 36.8%, of its original value. It depends on temperature, gravity and the mean molecular mass of the air.
