Answer 1

The correct option is A Barometer

A barometer is a scientific instrument used to measure atmospheric pressure. Air has a weight and presses against everything it touches as gravity pulls it to Earth.Meteorologist s use barometers to predict short-term changes in the weather. A rapid drop in atmospheric pressure means that a low-pressure system is arriving. Low pressure means that there isn’t enough force, or pressure, to push clouds or storm s away.
