From 2010–2015, there were no earthquakes in the state of Pennsylvania. On the other hand, southern California, which is similar in size to Pennsylvania, experiences nearly 10,000 earthquakes a year.
Which of the following statements might best explain this difference in the frequency of earthquakes?
Unlike California, Pennsylvania is not situated near a plate boundary where earthquakes are frequent.
Compared to California, Pennsylvania is in a time of minimal earthquakes, but will eventually have more.
Pennsylvania sits on top of more stable crust than California does, and is therefore resistant to earthquakes.
Pennsylvania has fewer seismographs than California and is unable to detect all of the earthquakes in the region.

Plate boundaries that have convergent motion, such as the one between the Australian and Pacific Plates, are sometimes called “destructive margins”.
What statement below BEST explains why this boundary is “destructive”?
As one plate subducts under the other, the plate that subducts melts into magma and is destroyed as a plate
As one plate moves away from the other, the crust spreads and new crust upwells.
As these plates collide, valleys form that can fill with water causing a loss of land.
As these plates slide past each other, they create a transform fault where some of the material erodes away.

The continental crust is thicker and more dense than the oceanic crust
An unusual type of fossil clam is found in rock layers high in the Swiss Alps of Europe. The same type of fossil clam is found in the Rocky Mountains of North America. From this, scientists conclude that:
glaciers carried the fossils up the mountains
the Rocky Mountains and Swiss Alps are both volcanic in origin
clams once lived in mountains, but have since evolved into sea-dwelling creatures.
the layers of rocks in which the fossils were found are from the same geologic age.

The volcanic eruptions at Mount St. Helens in Washington State and Kilauea in Hawaii have similarities and differences. At Kilauea, 100 homes have been destroyed since 1983, but there has been no loss of human life. However, when Mt. St. Helens erupted in 1980, it destroyed many homes, 57 people were killed very quickly and it wasn’t really a mountain any more.
What additional danger do you think the eruption at Mount St. Helens had that the eruptions at Kilauea do not?
slow moving poisonous gases
super hot slow lava flows
explosive eruptions
destruction of property
The United States mainland has thousands of miles of coastline along the Pacific Ocean, the Atlantic Ocean, and the Gulf of Mexico. Although each coastal area is subject to dangerous storms and flooding, it is mainly the Pacific Coast that plans for tsunamis.
Which of the following BEST explains the reason why the Pacific Coast prepares and the others coast don't?
The Pacific Ocean has the deepest water.
The Pacific Ocean has more earthquakes.
The Atlantic Ocean has the shortest coastline.
The Gulf of Mexico has the narrowest beaches.
One way to mitigate, or reduce, the impact of a volcanic disaster is to have plans in place to prevent loss of life and damage to property. Analyze the map of the state of New Mexico showing volcanic hazard areas (the yellow areas).
Compare the locations of Santa Fe and Roswell.
How should officials plan for volcanic mitigation in these two communities?
Only Roswell should plan for possible volcanic activity since it is in an area of high volcanic hazards.
Only Santa Fe should plan for possible volcanic activity since it is closest to an area of high volcanic hazards.
Both cities need to plan for possible volcanic activity since mostly all of New Mexico is subject to volcanic hazards.
Neither city needs to plan for possible volcanic activity since both cities are located far from areas of volcanic hazard.
The map shows the pattern of tsunamis in the United States. Consider San Francisco and Los Angeles as examples. Interpret the data to determine which city in California is more at risk.
If you oversaw planning for tsunami risks in California, which city would you focus your attention on and why?
Los Angeles, because it is overdue for a tsunami.
Los Angeles, because it is the larger of the two cities.
San Francisco, because it is farther east than Los Angeles.
San Francisco, because it has seen more tsunamis historically.
The table shows the top ten states predicted to experience the most flooding if sea levels rise one foot. Government planners have limited money to protect people, homes, and businesses.
If you were a national flood response planner, which region of the country might you focus on due to the data presented in the chart?
Pacific Coast
Atlantic Coast
Midwest States
Southwest States
Iceland sits on the mid-Atlantic Ridge and is slowly spreading apart. Recently, scientists tracked the movement of the two parts of Iceland by fitting two stations with GPS units in the towns of Reykjavik and Hofn and one basically in the center of the island.
Based on the data, the scientists calculated that Iceland was spreading apart at a rate of 1.8 cm/yr.
How did they calculate this rate?
It is the average change in distance of the two stations
It is the difference between the two average measurements of Reykjavik and Höfn.
It is the sum of the distance Reykjavik is moving from the center of the island and the distance Höfn is moving from the center of the island
It is the difference between the distance Reykjavik is moving from the center of the island and the distance Höfn is moving from the center of the island
Iceland sits on the mid-Atlantic Ridge and is slowly spreading apart. Recently, scientists tracked the movement of the two parts of Iceland by fitting two stations with GPS units in the towns of Reykjavik and Hofn and one basically in the center of the island.
Based on the location of the Mid-Atlantic Ridge on the map, what is one criterion the scientists had to meet in order to measure the spreading of Iceland?
The stations had to be on either side of the ridge.
The stations had to be at the same elevation in order.
The stations had to be the same distance from Europe.
The stations had to be in the same time zone in order.

There is evidence that a few major earthquake events caused additional spreading of 15 m over the last 1000 years, or about 1.5 cm/yr. Based on this new data, should the spreading rate be revised? In what way?
Yes, the spreading rate should be revised to about 3.3 cm/yr to include the earthquake event rate.
No, the spreading rate should remain at 1.8 cm/yr because earthquakes made the land closer together, not farther apart.
No, the spreading rate should remain at 1.8 cm/yr because nobody knows how to change the math to include the additional spreading.
No, the spreading rate should remain at 1.8 cm/yr because scientists do not revise their findings just because they get new information.
