🔍 Key Concepts

• High pressure systems and how they affect weather in mid-latitudes like the United States • Typical conditions associated with sinking (descending) air vs rising air • Relationship between cloud formation, humidity, and precipitation

💭 Think About

• Think about whether high pressure systems usually cause air to rise or sink, and how that affects cloud formation. • Consider which type of pressure system (high or low) is more often linked with storms, rain, and widespread clouds. • Ask yourself what the weather is usually like when a strong high pressure system is sitting over your area for a few days.

✅ Before You Answer

• Verify what kind of weather is typically associated with a low pressure system, and eliminate any choices that sound like that instead. • Check which options imply clouds and precipitation versus little cloud cover, and decide which fits high pressure better. • Confirm that the choice you select matches the idea of more stable, drier air rather than unstable, moist air.
