Question 8

Question 9 Which diagram shows the relative positions of Earth (E), the sun (S), and the moon (M) during a full moon? [Note: Diagrams are not drawn to scale]. A. C.   B. D.

Question 10 - 11 Use this map to answer question 11 and 12 Question 10 - 11 Use this map to answer question 11 and 12. The map below shows some of the major tectonic plates on Earth.

A. One tectonic plate is splitting apart into two plates. Question 10 What process is forming high non-volcanic mountains at location 1 on the map? A. One tectonic plate is splitting apart into two plates. B. Two tectonic plates are colliding and pushing together. C. One tectonic plate is sliding past another tectonic plate. D. Two tectonic plates are colliding and one is sliding under the other.

Question 11 A line of volcanoes occurs along the western coast of South America, near location 4. Based on the information about plate movement on the map, which process explains the formation of these volcanoes? A. subducting of one plate under the other causing melting of the lower plate B. sliding of one plate sideways past another resulting in friction and melting C. melting of crust because of plate movement over a “hot spot” D. rifting of a plate with lava filling in the resulting valley

12 and 13

A. layer 8 C. layer 4 B. layer 6 D. layer 2 Question 12 Based on observations, the paleontologist concluded that the layers had been undisturbed by geological activity. Which layer should have the oldest fossils? A. layer 8 C. layer 4 B. layer 6 D. layer 2

A. erosion C. folding B. faulting D. weathering Question 13 The paleontologist collected samples from a site that has the same rock layers as the original site but is located 5 kilometers away. Comparing the original site with the site shown above, what geologic process accounts for the difference in the arrangement of the rock layers at the two sites? A. erosion C. folding B. faulting D. weathering
