3 cards from this section. Quick, good the night before a test.
What is an aneroid barometer?
Think about how air pressure can affect the structure of a device.
How does an aneroid barometer differ from a mercury barometer?
Consider the materials used in each type of barometer.
What does an aneroid barometer primarily measure?
Look for what it's specifically designed to gauge.
True or False: Aneroid barometers use liquid to measure air pressure.
Think about the materials and mechanisms involved.
A hiker is using an aneroid barometer at sea level, and the pressure reading is 1015 hPa. If they ascend to a height of 1000 meters, what would you expect the new reading to be if the density of air decreases proportionally?
Use the known decrease in pressure with altitude!
Explain how an aneroid barometer can assist in predicting weather changes when moving from high-pressure to low-pressure systems.
Think about how the pressure reading varies with weather conditions.
