Q

What does a barometer measure?

🔍 Key Concepts

• Atmospheric pressure and how it affects weather systems • Difference between instruments that measure temperature, humidity, and pressure • Common weather instruments: thermometer, hygrometer, barometer

💭 Think About

• Which weather change is a barometer most useful for predicting: a heat wave, a cold night, a storm, or fog? • Think about which instrument a mariner would watch closely when concerned about approaching low-pressure systems and storms. • Match each choice with its usual instrument (thermometer, hygrometer, psychrometer, barometer) and see which one fits best.

✅ Before You Answer

• Be clear on what temperature is and which instrument usually measures it. • Recall which instrument is associated with humidity and dew point rather than pressure. • Confirm which option is directly related to changes in high and low pressure systems that bring wind and storms.
