Weather & Plates Review

Scientists recently discovered that rocks collected from the Franklin Mountains in West Texas 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

A teacher asks students to make a model of a transform plate boundary. The students use blocks to represent tectonic plates and slide the blocks past each other in the directions of the arrows as shown. Which event can the students best demonstrate with their model?

• an earthquake

• a volcanic eruption

• formation of a rift valley

• building up of a mountain

Rift valleys can form 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 form where a continental plate moves under an oceanic plate

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

• rift valleys form 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 shows a student's approximation of where the fault line crosses through the U.S. Students were asked to make maps predicting which way land would most likely move over thousands of years. Which map best predicts the likely movement of land along the fault line 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 both 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 diagram shows a model of the movement of two tectonic plates. When the plates collide, one 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

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

This topographic map represents the elevation of an area 100 years ago. At that time the highest point had an elevation of 214 m. The highest point has since eroded a total of 7 m. Which profile most likely represents the landscape today?
