An underwater earthquake can produce a large, destructive _______.

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”?

What evidence does THIS PICTURE provide that supports the continental drift hypothesis?

Which statement best describes the continental and oceanic crusts?

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:

Which of the following word diagrams correctly represents the layers of the Earth?

Using the picture shown here, where would you expect to find the youngest rocks?

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?

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?

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?

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?

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?

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?

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?

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.

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?

In 2005, Japanese scientists and engineers built a giant earthquake shake table in response to the deadly 1995 earthquake near Kobe, Japan. A shake table is a large platform that can move in three directions, simulating an earthquake. 4 different houses (some with safety improvements and some did not) were tested until they collapsed.

Based on the results of the investigation, which house withstood the most shaking?

Based on the results of the investigation, what claim can be made regarding older homes compared to newer homes?

Based on the results from the investigation, how should engineers plan to improve the stability of older homes in Japan?

Where would a person likely experience an earthquake?

What is the best place where a person NOT likely experience an earthquake?

What layer of Earth do we see convection currents occurring?

What type of boundary would it be if there is a large mountain at the boundary?

What type of boundary would it be if there is a rift valley?

What type of boundary is sea floor spreading?

What type of boundary creates a deep sea trench?

Which one of the pictures outlines the Ring of Fire?

The continuous cycle of heating, rising, cooling, and sinking that occurs in the mantle is called _________.

Iceland is an ideal place to study seafloor spreading because:

All of the following will improve safety factors during an earthquake EXCEPT _______.

Which of the Hawaiian Islands has the greatest probability of having a volcanic eruption?

If each island formed as the plate moved over the magma source in the mantle as shown in diagram 2, where would the next volcanic island most likely form?

One climate clue used to support the theory of continental drift is/are _______

Matching ______ on different continents are evidence of continental movement.

What type of boundary will produce volcanoes?
