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

Rift valleys can from when fractures in Earth's crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?

• Rift valleys from where a continental plate moves under an oceanic plate

• Rift valleys form where a plate slides horizontally past another plate

• Rift valleys from where two plates move away from each other.

• Rift valleys form where an oceanic plate moves under another oceanic plate.

The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years.

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 image shows a plate boundary. Arrows have been added to indicate the movement of the plates.What plate boundary feature is also shown?

• A ridge formed by an inactive convergent boundary

• A valley forming at an active divergent boundary

• A fault forming at an active transform boundary

• A volcano formed by an active transform boundary

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
