Which of the following topographic features could be directly formed by the movement of the Earth's plates? I. midocean ridges II. mountains III. sand dunes IV. coral reefs A. I, II, and III only B. II, III, and IV only C. I and II only D. II and III only Question #2 Image from The world map above shows the locations of tectonic plate boundaries (black lines) and active volcanoes (red dots). Based on this map, volcanoes most commonly form A. along Earth's equator. B. in Earth's polar regions. C. near tectonic plate boundaries. D. in the middle of tectonic plates.

2 Question #3 The Atlantic Ocean is currently growing wider as its floor enlarges due to the process of sea-floor spreading. In sea-floor spreading, pieces of oceanic crust A. move down in a subduction zone. B. move together along a convergent plate boundary. C. move apart along a divergent plate boundary. D. move sideways against each other along a transform plate boundary. Question #4 What term best describes the geologic event taking place in the above illustration? A. erosion B. plate convergence C. seafloor spreading D. weathering Question #5 The older theory of continental drift suggested A. that continents are fixed in position and considered to be permanent features on the Earth's surface. B. that all the continents drift at the same rate and in the same direction. C. that there was once a supercontinent and the huge landmass was broken into continents that drifted apart. D. that the configuration of the continents today will be the same in 200 million years. Question #6

3 The theories of continental drift and sea-floor spreading combined to make the theory of. A. rejoined continents B. Pangaea C. plate tectonics D. supercontinents Question #7 Two hundred and twenty-five million years ago, all of today's continents were part of a single continent known as Pangaea. The map below shows the positions of some of these continents. This image is courtesy of the USGS. There is a significant amount of evidence that can be used to support the theory that Pangaea existed. Which of the following explains how the map shows evidence for the existence of Pangaea? A. The continents' shapes do not fit together very well, and each continent has completely different fossils. B. The continents' shapes fit together well, and some continents have the same fossils. C. None of the continents had similar climates to each other in the past. D. All of the continents had identical climate conditions in the past. Question #8 The early hypothesis of was based on observations that suggested continents were once joined together. Later, the theory of explained why large pieces of Earth's surface move around and how many of Earth's features form. A. continental drift; plate tectonics

4 B. plate tectonics; gravitational force C. gravitational force; continental drift D. plate tectonics; continental drift Question #9 Earth 250 million years ago Earth Today The images above show how the Earth's continents looked 250 million years ago and how they look today. The change in the continents' positions is explained by the modern theory of plate tectonics.

5 The theory of plate tectonics developed in part from an earlier hypothesis about how continents move. What is the name of this earlier hypothesis? A. evolution B. continental drift C. natural selection D. earthquake development Question #10 The symbols found on the map below indicate where fossils have been found in the same layer of sediment. Each symbol indicates a different type of fossil. What do the locations of the fossils suggest? A. The continents' locations have remained constant throughout time. B. Each continent has completely unique plant and animal life. C. Similar fossil types are never found on different continents. D. The continents were once connected to each other. Question #11 Different types of crust react in different ways when they collide with another piece of Earth's crust. Which of the following plate collisions would most likely result in the formation of the most extensive mountain range? A. a piece of continental crust and a piece of oceanic crust meeting at a divergent boundary B. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary C. two pieces of continental crust meeting at a convergent boundary D. two pieces of oceanic crust meeting at a transform boundary

6 Question #12 What is Pangaea? A. A mid-ocean ridge than runs from north to south along the Atlantic Ocean's floor. B. A species whose fossilized remains in Africa led to the hypothesis of continental drift. C. A complex theory that explains the motions of continents and many of Earth's features. D. A single, large landmass in which all of Earth's continents were once joined.
