(From http://www.nysedregents.org/testing/scire/es-607.pdf) The geographic position of Australia on Earth’s surface has been changing mainly because A. the gravitational force of the Moon has been pulling on Earth’s landmasses forcing them to move. B. the tilt of Earth’s axis has changed several times shifting Earth’s landmasses. C. Earth’s rotation has spun Australia into different locations. D. temperature differences have been creating convection currents in Earth’s interior moving landmasses. 2nd Item Specification: Identify the evidence for seafloor spreading.

Most volcanoes are located under ocean water and found near the continental shelves. B. Paleomagnetic studies of the ocean floor demonstrate that the orientation of Earth’s magnetic field has remained constant. C. Fossils of marine organisms can be found at high elevations on continents. D. The age of the seafloor rock increases as the distance from the mid-ocean ridge increases. 7. Base your answer to the question on the cross section below, which shows an underwater mountain range in the Atlantic Ocean. The oceanic bedrock is composed mainly of basalt. Points X and Y are locations in the bedrock that have been diverging at the same rate. The movement of the North American Plate and Eurasian Plate is shown by the two arrows.

The basalt at location X is younger than the basalt at location Y. Both locations have the same magnetic orientation. B. The basalts at location X and Y are the same age. Both locations have the same magnetic orientation. C. The basalt at location X and Y are the same age. Location X has normal magnetic orientation and location Y has reversed magnetic orientation. D. The basalt at location X is older than the basalt at location Y. Location X has reversed magnetic orientation and location Y has normal magnetic orientation. Depth of Knowledge Level 2 8. Base your answers to question on the map below. The map shows the continents of Africa and South America, the ocean between them, and the ocean ridge and transform faults.

A. Graph 1 B. Graph 2 C. Graph 3 D. Graph 4 9. The diagram below represents the pattern of normal and reversed magnetic polarity and the relative age of the igneous bedrock composing the ocean floor on the east side of the MidAtlantic Ridge. The magnetic polarity of the bedrock on the west side of the ridge has been deliberately left blank.
