Earth Science:Geology, andtheUniverse theEnvironment, Earth 1. In what direction is the Pacific Plate moving? 1. Which diagram shows a divergent boundary? How do the plates move relative to each other at this type of boundary? west or northwest A; The plates move apart from one another. 2. Are the Pacific Plate and the Antarctic Plate moving toward each other, away from each other, or past each other? Explain your answer. 2. At a divergent boundary, what feature forms when two oceanic plates are involved? When two continental plates are involved? The arrows along the plate boundaries point in opposite directions, indicating that the Pacific Plate and the Antarctic Plate are moving away from each other. an ocean ridge; a rift valley 3. Which diagram shows oceanic-oceanic convergence? Describe what occurs at this 3. What type of boundary separates the South American Plate from the Nazca Plate? Explain your answer. type of plate boundary. Arrows along the boundary between the South American Plate and the Nazca B; Two oceanic plates converge. One of the plates is subducted under the other. Plate point toward each other, indicating that the boundary between these two A deep-sea trench forms and magma rises to form an arc of volcanic islands. plates is a convergent boundary. 4. The Himalayas are mountains that are forming as a result of the collision of the Indian and Eurasian continental plates. Which diagram shows a plate boundary like 4. Describe the relative motion between the North American Plate and the Pacific Plate. the one involved in the formation of these mountains? These two plates are sliding past each other in some areas and converging D

in others. 5. Which diagram shows oceanic-continental convergence? Describe what occurs at this type of plate boundary. 5. Between which plates is the relative motion the fastest? C; An oceanic plate collides with a continental plate. The oceanic plate, which is between the Nazca Plate and the Pacific Plate denser than the continental plate, subducts under the continental plate to form 6. Would you predict that, over time, the distance between New York and Miami will increase, decrease, or stay the same? Explain your answer. a trench and volcanoes. The distance between New York and Miami will likely stay the same because 6. Which diagram shows a transform boundary? Describe what occurs at this type of plate boundary. they are on the same plate. E; Two plates slide horizontally past each another, and crust is deformed or 7. Would you predict that, over time, the distance between New York and Lisbon, a city is southern Europe, will increase, decrease, or stay the same? Explain your answer. fractured. Long faults and earthquakes are characteristics of these boundaries. The distance between New York and Lisbon will increase because the cities are
