The concept of isostacy states that high-density rock will stand higher than low-density rock, which explains the formation of subduction zones.
   a. True
   b. False

Question 2

Earths crust is thinner than its mantle.
   a. True
   b. False

Question 3

You have been hired by a major national firm with offices in all American metropolitan areas. To encourage diversity, the firm believes that new employees should spend their first year in an office in a region in which they have never lived.
 
  Which city would you choose and why? What natural hazards will you need to be mindful of? How will you make an intelligent choice of how and where to live based on the positive qualities of the area and the possibility that you may encounter a natural disaster?
   
  What will be an ideal response?

Question 4

A watercourse named Buffalo Bayou runs through the city of Houston, Texas from east to west, passing through residential and industrial areas and the edge of the tall buildings of downtown. In the residential area, the Bayou is surrounded by a wide park, and the level of the water is typically 20 feet below the level of the streets around it. The river has overflowed its banks and caused ground-floor damage to residences nearby; most recently in 1999 and 2015. The bayou has flooded 10 times in the last century.
 
  You are an insurance adjuster, and have just paid a claim for 20,000 (the maximum allowed in the policy) for a homeowners loss. The homeowner is upset and says My flood premium has been 2,000 since the flood of 1999, and now youre paying me only 20,000 back? I think my premium is too high
 
  Explain to the homeowner why the premium is appropriate.
   
   
  What will be an ideal response?

Question 5

Mangrove trees grow in inlets and lagoons along the U.S. coastline from the Texas Gulf coast to the Florida Atlantic coast. These trees extend wide networks of roots in shallow water and play a major role in reducing damage due to storm surges. Mangroves grow in the form of large shrub-like trees, about 10 feet tall. The area inside a grove cannot be easily navigated on foot and generally smells unpleasant due to decaying marine life and plants.
 
  Cutting or damaging mangrove trees is illegal in most areas without special permission, and this fact is advertised with large educational signs at key sites, including public boat ramps and nature areas. Businesses and homes can be built behind a grove of mangrove trees as long as the trees are not disturbed. Studies clearly show that the presence of mangroves reduces the damage done during hurricanes and tropical storms.
 
  Briefly describe how this situation involves Land-Use Planning, Insurance, the Role of Government, and Public Education in positive ways.
   
  What will be an ideal response?

Question 6

Suppose a professor teaching from your textbook makes the comment that The media responds to what is sensational, and typically pays more attention to the least deadly natural disasters. Consider what you have learned about the number of deaths associated with different types of disasters, and explain what the professor means by the statement
   
  What will be an ideal response?

Question 7

Consider Figure 1-4 from the text. The top line represents the 10-year average total losses.
   
  A UN researcher is interested in describing the expected cost of natural disasters over the next twenty years. Should the researcher focus on the information in the bar charts or the lines? Would it be appropriate for the researcher to use a linear model in their forecast? Explain your answer clearly in the context of the graph.
   
  What will be an ideal response?

Question 8

The acronym for the federal agency responsible for disaster relief is _______________.
  Fill in the blank with correct word.

Answer to #1

ANSWER: False

Answer to #2

ANSWER: True

Answer to #3

ANSWER: Here is a sample response:
Ive always wanted to live in San Francisco, but the danger of earthquakes is very high. Even though the damage due to earthquakes is low, a quake in the city would be very dangerous. I will pick Sacramento, where the danger of a catastrophic earthquake is lower, but still be close enough to visit the city often.

I would live in Phoenix, since my fathers family is from there. Drought and heat will be my biggest concerns. I should make sure that I have a way of storing water for drinking in a long drought, and maybe choose a house that is designed to be cool without always using the air conditioner. I should definitely learn about any other steps I should take to avoid problems.

A successful answer must:
- connect a city with a hazard reasonable for the area.
- present at least one clear way of mitigating the effect of the disaster, and
- demonstrate that the student is proposing a reasonable balance between positive factors and the type and scope of disaster.

Answer to #4

ANSWER: The last flood event was sixteen years ago, but on average the Bayou floods every ten years. The time between floods is unpredictable, as they do not occur regularly. On the average, the company may have to pay the homeowner 20,000 every ten years, and the 2,000 premium is based on that. Its possible that the Bayou will flood next year, and the company will have paid more than the homeowner has paid in premiums.

Answer to #5

ANSWER: The government is acting fairly to keep the mitigating effect of the mangrove trees without otherwise restricting the way the adjacent land is used. This is fair since it reduces danger to a large population without unfairly restricting the use of the land behind the barrier.

Businesses which need open access to water will have to apply for special permits or locate elsewhere. Local land-use planners can evaluate whether a request to clear mangroves from an area is worth the increased danger. Planners can also designate areas where mangroves do not grow as sites of marinas or other businesses that require access to water.

The placement of signs in many areas explains to the general public why the trees are important, even though they are not a pleasant place to walk, and have an unpleasant smell. The public is more likely to support protection of mangroves when they understand their importance in preventing damage from hurricanes.

Insurance companies will understand that properties protected by mangroves can be expected to suffer less loss in a disaster. The companies may encourage the government efforts, or offer better rates to businesses and homes in protected areas. They will also benefit by having a lower chance of a disaster reaching an unexpected cost.

Answer to #6

ANSWER: Disasters like volcanoes, earthquakes, and hurricanes are sensational in the sense that they are sudden, dramatic events with strong imagery. These disasters represent a small percentage of deaths from natural hazards. The deadliest natural disasters include drought and winter weather. These disasters occur over a long time and do not have a sensational sense of drama and imagery.

Answer to #7

ANSWER: The researcher should use the 10-year average (indicated by the lines on the graph) to predict what will happen over the next ten years. Since the type and effect of natural disasters are unpredictable, the yearly losses are very variable. The 10-year average is a more accurate summary of what will happen over time.

The 10-year averages are increasing in a steady fashion that looks like small variations around a linear trend. A linear fit is appropriate.
