1 Which statement best describes a natural hazard?
- A human-made accident with no environmental component
- A natural Earth process that may threaten people or property
- Any event that always becomes a catastrophe
- A risk that cannot be studied scientifically
The text treats natural hazards as natural Earth processes that can have harmful impacts on society.
2 What best distinguishes a catastrophe from a disaster?
- A catastrophe has smaller impacts
- A catastrophe is limited to rural areas
- A catastrophe is a larger-scale event that overwhelms coping capacity
- A catastrophe only refers to volcanic eruptions
The text distinguishes more extreme, overwhelming events as catastrophes.
3 The scientific study of natural hazards can help predict future hazardous activity by using past frequency, occurrence patterns, and precursor events.
- True
- False
One of the book’s fundamental concepts is that science helps us predict hazards using evidence from monitoring, mapping, and past patterns.
4 Which factors are central to risk analysis? Select all that apply.
Select all that apply
- Probability of the event
- Consequences of the event
- Color of the local bedrock
- Exposure of people and property
Risk analysis focuses on the likelihood of an event and its consequences; exposure helps determine those consequences.
5 Which Earth-system cycle is most directly tied to earthquakes and volcanoes?
- Hydrologic cycle
- Tectonic cycle
- Carbon cycle
- Biogeochemical cycle
The tectonic cycle explains plate movement and many internal geologic hazards.
