ESS3B - Natural Hazards

Paul Anderson explains natural hazards, their potential to become disasters, and how they can be predicted and mitigated. He uses historical examples like the 1906 San Francisco earthquake and the eruption of Mount St. Helens to illustrate these concepts. The video also discusses the impact of population growth and climate change on natural disasters and provides guidance on teaching these topics in schools.

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

• A natural hazard is a human-made event, while a natural disaster is natural.

• A natural hazard occurs globally, while a natural disaster is local.

• A natural hazard is a potential threat, while a natural disaster is the actual event causing damage.

• A natural hazard is always predictable, while a natural disaster is not.

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

• Volcano

• Deforestation

• Tsunami

• Earthquake

Why can't we eliminate natural hazards?

• They are caused by human activities.

• They are natural processes of the Earth.

• They are too expensive to manage.

• They occur only in remote areas.

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

• By monitoring air quality changes.

• By observing a massive bulge forming on the mountain.

• By detecting unusual animal behavior.

• By measuring increased rainfall in the area.

What is a key challenge in predicting earthquakes?

• Lack of technology to detect them.

• Unpredictability of the Earth's movements.

• Inability to measure their magnitude.

• They occur only in uninhabited areas.

Which natural hazard is most likely to occur in the Midwest of the United States?

• Tornadoes

• Wildfires

• Hurricanes

• Heat waves

As global temperatures rise, which of the following is expected to increase?

• Severity of storms

• Frequency of earthquakes

• Number of volcanoes

• Occurrence of tsunamis
