Natural Hazards

The best definition of the relationship between a natural hazard and a natural disaster is:

• A natural disaster occurs in the northern hemisphere whereas a natural hazard occurs in the southern hemisphere
• They are the same thing
• A natural hazard is the potential of an incident occurring whereas a natural disaster is declared when there has been loss of human life or property damage
• A natural disaster is more extreme than a natural hazard

Which is true of natural hazards?

• Most natural hazards can be prevented.
• It is impossible to prepare for a natural hazard.
• Most tsunami damage happens far inland.
• Many natural hazards are caused by weather.

To stay safe from volcanoes, it is important for people to test

• evacuation routes.
• mudflow speed.
• soil temperatures
• tsunami systems

What does the Pacific Tsunami Warning System use to detect tsunamis?

• radio signals in the air
• ripples in the water
• sensors on the ocean floor
• behavior of marine animals

Which type of map shows the elevation of an area?

•  mountain maps
• political maps
• topographic maps
• climate maps 

Which of the following is not a type of natural hazard?

• volcanic eruption
• earthquake
• blizzard
• mountain

Some engineers want to see how different building designs might withstand a strong earthquake. What is the best way to determine this?

• Test one building during different earthquakes.

• Study past earthquake strengths on a graph.

• Test multiple model buildings for one model earthquake.

• Construct a real building to observe during an earthquake.
