Question 1

What is the importance of the idea that "hazards are repetitive"?

Accepted Answer

A)  We need to look to past events to understand what is probable for the future. 
B)  If something has already happened, like a volcanic eruption, then we won't need to worry about it. 
C)  New events will probably happen exactly like old ones, so we need to be prepared. 
D)  Hazards keep happening constantly in an area, so people already know how to react to them.

Question 2

The rock cycle shows that rocks are very old and not much use in understanding today's problems.

Accepted Answer

A) True 
 B)False  False

Question 3

Choose any natural hazard and describe why it is a hazard. Next, describe how it might cause a disaster and how it might become a catastrophe.

Accepted Answer

Earthquakes cause the ground to shake and can cause buildings to collapse, which can result in death and destruction. Earthquakes can cause a disaster if a large earthquake occurs near a populated area. It can become a catastrophe is the buildings are weakly constructed and therefore easily collapsed.

C)  Deserts are likely to expand. 
D)  Warmer ocean water will increase storm activity. 
E)  All of the above are impacts of climate change.

Accepted Answer

A) True 
 B)False

Question 7

Low magnitude (less damaging) natural hazards tend to occur more frequently than high magnitude (more damaging) natural hazards.

Accepted Answer

A) True 
 B)False

Question 8

In the past, many people believed that natural hazards were random events that took place on the Earth's surface. Explain why this is not true and how scientists know where hazards might occur. Explain how thinking of hazards scientifically will help communities and average people cope with the disaster.

Accepted Answer

We know that earthquakes and volcanic er

B)  A scientific hypothesis may address a question such as why did a natural disaster occur in a certain area. 
C)  Scientific hypotheses can be tested by other scientists. 
D)  One of the failures of the scientific method is when a hypothesis is disproved and has to be rejected.
