A barometer measures atmospheric pressure. Knowing the atmospheric pressure can help people predict the weather. Study the picture of the barometer. It shows an atmospheric pressure of about 28.3 inches of mercury.

Question

Based on the readings of the barometer in the picture, what type of weather is most likely happening where the picture was taken?
A.
The weather is stormy.
B.
The weather is fair.
C.
The weather is very dry.
D.
The weather is changing.

Answer 1

A barometer reading of about 28.3 inches of mercury typically indicates lower atmospheric pressure, which is associated with stormy or unsettled weather. Higher pressure readings (around 30 inches or more) generally suggest fair weather. Therefore, based on the reading of 28.3 inches, the most likely weather where the picture was taken is:

A. The weather is stormy.
