Understanding Natural Hazards

Paul Anderson explains natural hazards, their potential to become disasters, and how they can be predicted and mitigated. Using examples like the 1906 San Francisco earthquake, he illustrates the impact of natural hazards. He discusses the role of population growth and climate change in increasing natural disasters. The video also covers educational strategies for teaching about natural hazards at different school levels.

What is the main difference between a natural hazard and a natural disaster?

• A natural hazard can lead to a natural disaster.

• A natural disaster is a potential threat.

• A natural hazard is always man-made.

• A natural disaster occurs without any warning.

Which of the following is NOT an example of a natural hazard?

• Earthquake

• Volcano

• Tsunami

• Traffic jam

Why is retrofitting buildings important in areas prone to earthquakes?

• To make them look more modern.

• To reduce the damage caused by earthquakes.

• To increase their market value.

• To prevent them from being used.

How were scientists able to predict the eruption of Mount St. Helens?

• By listening to local folklore.

• By using satellite imagery.

• By observing a massive bulge on the mountain.

• By measuring the temperature of the ocean.

What is a key challenge in predicting earthquakes?

• They can be predicted accurately using radar.

• The exact timing of the Earth's slip is unpredictable.

• They only occur in uninhabited areas.

• They are less frequent than other natural hazards.

How does population growth affect natural disasters?

• It has no impact on natural disasters.

• It makes natural disasters less severe.

• It increases the potential damage from natural disasters.

• It decreases the frequency of natural disasters.

Which of the following is a result of increasing global temperatures?

• Decrease in severe storms.

• Increase in severe storms.

• No change in weather patterns.

• Reduction in natural hazards.

What should be emphasized when teaching lower elementary students about severe weather?

• Severe weather occurs randomly.

• Severe weather occurs in specific times and places.

• Severe weather is always predictable.

• Severe weather is not dangerous.

What is an important concept for middle school students to understand about natural hazards?

• They can be completely eliminated.

• They can be predicted and prepared for.

• They are only a recent phenomenon.

• They are not influenced by human activity.

Why is it important for high school students to learn about the history of natural hazards?

• To find ways to prevent them entirely.

• To understand that they are a part of human history.

• To learn how to create natural hazards.

• To know that they will never occur again.
