Question 1112Navigation General

The correct answer is B) in which the pressure of the air is measured. An aneroid barometer is a type of barometer that measures atmospheric pressure without the use of liquids. It uses a sealed capsule or diaphragm that expands and contracts in response to changes in air pressure. This allows the aneroid barometer to provide a direct reading of the current air pressure, which is a critical piece of information for maritime navigation and weather forecasting. The other answer choices are incorrect because an aneroid barometer is not used to measure wind speed (A), determine storm direction (C), or measure wave height (D). It is specifically designed to provide accurate air pressure readings.
