🔍 Key Concepts

• Isobars on a weather map connect points of equal WHAT? • How mariners use isobars to understand highs and lows on a surface weather chart • Difference between pressure, wind, and temperature lines on maps (isobars vs isotherms vs isotachs)

💭 Think About

• Ask yourself: when you look at closely spaced isobars, what weather feature are you really interpreting? • Think about what a barometer measures on the bridge—those same units are what the numbers on isobars show. • Which of the options would be expressed in units like millibars (mb) or hectopascals (hPa)?

✅ Before You Answer

• Match the term "bar" in "isobar" with the physical quantity it refers to. • Remember that isotherms are lines of equal temperature and isotachs are lines of equal wind speed—rule out those uses. • Verify which choice is commonly written on surface weather charts as values like 1004, 1008, 1012, 1016.
