Question

As we go up from the surface of earth, the atmospheric pressure ________due to ______ in column of air above us.

• A. decreases, increase
• B. decreases, decrease
• C. increases, increase
• D. increases, decrease

Answer 1

The correct option is B decreases, decrease

The pressure at any level in the atmosphere can be interpreted as the total weight of the air column above a unit area at any altitude.
At higher altitudes, there are fewer air molecules above a given surface than a similar surface at lower levels.
Hence, we can say that the atmospheric pressure decreases with altitude.
