🔍 Key Concepts

• Barometric pressure and how it relates to approaching or departing weather systems • Difference between rapid pressure changes and slow, steady changes • What a barometer actually measures (pressure), not specific phenomena like fog or rain

💭 Think About

• Ask yourself: Does a barometer directly ‘measure’ rain, fog, or wind, or does it measure something more general that can lead to changes in those? • Consider what the word rapid tells you about how quickly conditions might be changing in the atmosphere. • Think about which choice describes a specific type of weather versus a more general indication of changing conditions.

✅ Before You Answer

• Verify which option refers to a general change in conditions rather than a specific event like rain or fog. • Eliminate any choices that suggest the barometer alone can predict exact weather events or timing (e.g., “within six hours”). • Remember that a rapid rise or fall usually signals that conditions are likely to change, not necessarily that wind must decrease or fog must form.
