🔍 Key Concepts

• Warm vs. cold air mass is defined by the temperature of the air compared to the surface it is moving over • An air mass is named (maritime, continental, polar, tropical) by where it formed, but it is called warm or cold by what it is moving over now • Surface temperature vs. air temperature is more important here than the absolute temperature in °F

💭 Think About

• Think about what the term warm air mass is being compared to: warmer than what? • Which choice describes a relationship between the air mass temperature and the temperature of the ground or water beneath it? • Do any of the answers mention where it formed instead of what it is currently moving over?

✅ Before You Answer

• Verify which option deals with the temperature difference between the air mass and the surface beneath it • Eliminate any choices that rely only on pressure (high or low) without talking about temperature relative to the surface • Eliminate any option that uses a fixed temperature like 70°F instead of a comparison to the surface
