🔍 Key Concepts

• Weather fronts as boundaries between air masses • Characteristics of air masses (temperature and humidity) • How pressure systems (highs and lows) differ from fronts

💭 Think About

• Ask yourself: What exactly defines a front — is it about temperature differences, pressure patterns, or cloud formations? • Think about how meteorologists draw fronts on weather maps: what condition has to be present between the two sides of the front line? • Consider whether a front can exist if the air on both sides has the same basic properties.

✅ Before You Answer

• Verify how a front is defined in basic meteorology texts (key words: boundary, contrasting properties). • Check which choices describe meeting of air masses versus just pressure patterns or clouds. • Eliminate any option where the air masses have no meaningful contrast in temperature or other properties.
