Which change is least likely to result from future plate movement?

Scientists recently discovered that rocks collected from the Franklin Mountains in West Tests and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of--

• coastal erosion

• plate tectonics

• ocean currents

• glacial melting

One of the key pieces of evidence that supports the theory of plate tectonics is the puzzle fit of the continents. The theory was weakened by areas which lacked an exact fit. Later, scientists realized that the continental shelf should be included in the theory. Which statement explains why the continental shelf should be included?

• Coastlines of continents have not changed over time.

• Coastlines have been eroded over time, but the continental shelf is less affected by erosion and thus allows a better fit.

• Coastlines changed as the continents broke apart and the continental shelf remained unchanged.

• The continental shelf has grown over time and fills in the gaps, allowing for a better puzzle fit.

Which statement best describes the geologic process that is most likely responsible for the formation of mountains?

• They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.

• They are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults

• They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.

• They are along a plate boundary in which plates diverged in the distance past, allowing new rock to build up.

A mid- ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America. Which statement best describes the relative motions of the Pacific and Nazca plates?

• The Pacific and Nazca plates are moth moving to the east.

• The Pacific and Nazca plates are both moving to the west

• The Pacific plate is moving to the west, and the Nazca plate is moving to the east.

• The Pacific plate is moving to the east, and the Nazca plate is moving to the west.

The map shows the locations of four active volcanoes in the Caribbean Sea. What do these volcanoes indicate about plate tectonics in the region?

• The volcanoes form an island arc, indicating a converging plate boundary

• The volcanoes form a line, indicating a diverging plate boundary.

• Two plates are moving past each other, causing faulting and magma formation.

• Two plates are moving apart, creating new seafloor

The diagram shows a model of the movement of two tectonic plates. When the plates collide, on plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce-

• fossil layers

• volcanic islands

• deep-sea sediment

• seafloor spreading

• Divergent boundary

• Subduction boundary

• Convergent boundary
