测验总得分: 0 / 18 题

Part A: Before You Watch · 气旋术语匹配 (P.94)

1. What is the central, calm area around which a hurricane rotates?

2. Over what kind of ocean water do hurricanes typically originate and draw immense thermal energy?

3. What minimum sustained wind speed qualifies a tropical storm as a Category 1 hurricane?

4. What coastal phenomenon represents the deadliest aspect of approaching hurricanes?

Part B: While You Watch · 视频事实细节 (P.94)

1. During which season do hurricanes predominantly form in the northern hemisphere?

2. What atmospheric disturbance initiates the chain reaction that can build into a hurricane?

3. What surrounds the calm eye of the hurricane, containing the most violent winds and heaviest rain?

4. What factor primarily determines the Saffir-Simpson hurricane category scale (1 to 5)?

💡 Critical Thinking & Discussion · 自然灾害防御与全球响应 (P.94)

Natural Hazards Impact: Apart from hurricanes, what other natural disasters threaten human coastal settlements, and why do early warning systems save thousands of lives?

Teacher's Guide · 权威参考观点

Tsunamis, earthquakes, volcanic eruptions, and tornadoes pose extreme threats. The devastating 2004 Indian Ocean tsunami killed over 230,000 people due to the absence of coastal early warning systems. Timely alerts and fortified infrastructure are paramount.
