• Barometric pressure trends over time • How rapid changes in pressure relate to approaching storms or clearing weather • Difference between absolute pressure and pressure tendency

💭 Think About

• If you had only one pressure-related clue to judge whether weather is improving or worsening in the next 12–24 hours, which would help you most? • Think about a falling vs. rising barometer: what matters more, the number shown right now, or what it has been doing over the last few hours? • Which choice reflects not just a value, but information about future change in conditions?

✅ Before You Answer

• Identify which option tells you both how pressure is changing and how fast it is changing. • Eliminate any choices that are more about labels or single measurements than about trends over time. • Remember that mariners watch the tendency of the barometer to anticipate fronts and storms.
