Which best describes why winds at the beach change direction between day and night?

• because the temperatures over land and over water change

• They have the same kinds of severe weather.

Which correctly compares low- and high-pressure weather systems?

• A low-pressure system usually brings cool dry air and clear skies, while a high-pressure system brings clouds and precipitation.
• A low-pressure system usually brings clouds and precipitation, while a high-pressure system brings cool dry air and clear skies. 
• A low-pressure system usually brings warm dry air and clear skies, while a high-pressure system usually brings warm moist air and precipitation.

Which best explains why North Carolina’s winter weather could vary from what is normally predicted during a La Niña event?
