1: The correct answer is lower central air pressure. When the central air pressure of a hurricane decreases, it causes the storm to increase in strength.
2: The correct answer is wind speed. The Saffir-Simpson scale categorizes hurricanes based on their maximum sustained wind speeds.
3: The correct answer is the Coriolis effect. The Earth's rotation causes hurricanes in the Northern Hemisphere to rotate counterclockwise.
4: The correct answer is Well-constructed frame homes could have damage to the roof, shingles, and vinyl siding. A Category 1 hurricane generally causes minimal damage, such as roof damage and siding damage, to well-constructed homes.
