  1. Use the diagrams below showing the same region of the Earth’s surface at two different time intervals to answer the question that follows.

Diagrams I and II show the same region of the Earth’s surface at two different times in the geologic past. Diagram I was 250 million years ago and Diagram II was the same region 150 million years ago. Which statement best explains the basic cause of the changes that occurred in this region?

  1. Temperature changes caused melting of polar ice caps.
  2. Meteor impact on the crust caused widening of the valley.
  3. Mantle convection currents caused crustal movement.
  4. Weathering and erosion caused widening of the valley.

2nd Item Specification: Identify geologic events that result from movements of crustal plates.

Depth of Knowledge Level 1

  1. Use the diagram below to answer the question.

World Map of Major Earthquake Epicenters

(From

Major earthquakes occur

  1. in specific belts within the crust.
  2. along the mantle-core boundary.
  3. in the centers of the continents.
  4. randomly over the Earth’s surface.
  1. Use the diagram below to answer the question.

(From

Each dot on the map represents an Earth scientist’s data. These dots most likely represent zones of frequent

  1. fossil correlations.
  2. crustal activity.
  3. hurricane paths.
  4. meteor impacts.

  1. Use the diagram below to answer the question.

World Map of Major Earthquake Epicenters

(From

How would a map showing the location of active volcanoes compare to the map showing the location of earthquake epicenters?

  1. Only a small percentage of volcanoes would be in the same regions as the epicenters.
  2. A large percentage of volcano locations would be in the same regions as the epicenters.
  3. There would be no match between the locations of the volcanoes and epicenters.
  4. The location of the volcanoes and epicenters would only match in the ocean regions.

  1. Use the diagram below to answer the question.

(From

What type of plate boundary is established between India and the Eurasian Plate?

  1. Ocean-Ocean convergence resulting in the formation of a trench.
  2. Ocean-Ocean convergence resulting in the formation of an underwater mountain range.
  3. Continent-Continent convergence resulting in the formation of a trench.
  4. Continent-Continent convergence resulting in the formation of a mountain range.

Constructed Response E.8.C.4 Score Rubric:

3 points / Response addresses all parts of the question clearly and correctly.
  1. Volcanoes and earthquakes are found in similar regions or zones around Earth. There is a large concentration of these two events along the west coast of North and South America extending around the Pacific Ocean – Ring of Fire. Geologic events such as earthquakes and volcanoes are most often found near the edges of lithospheric plate boundaries, as here is where plate motion strains/stresses the rocks.
  1. Plate boundaries are crustal zones of weakness providing an easier path for magma from the mantle to head toward Earth’s surface. The center of lithospheric plates are more stable, and less likely to have crustal activity.

2 points / Response addresses all parts of the question and includes only minor errors.
1 point / Response does not address all parts of the question.
0 points / Response is totally incorrect or no response provided.
