6 < BackNext >PreviewMain Chapter 4 CRCT Preparation 3. Volcanic activity on Earth’s surface most likely results in the formation of which of the following types of rock? A intrusive igneous rock B extrusive igneous rock C clastic sedimentary rock D chemical sedimentary rock

7 < BackNext >PreviewMain Chapter 4 CRCT Preparation 3. Volcanic activity on Earth’s surface most likely results in the formation of which of the following types of rock? A intrusive igneous rock B extrusive igneous rock C clastic sedimentary rock D chemical sedimentary rock

8 < BackNext >PreviewMain Chapter 4 CRCT Preparation 4. How does clastic sedimentary rock form? A Rock fragments are cemented together by a mineral such as calcite or quartz. B Dissolved minerals crystallize out of solution in water to form solid minerals. C Heat and pressure turn partially decomposed plant material into rock. D Skeletons of sea animals that collected on the ocean floor are cemented together.

20 < BackNext >PreviewMain Chapter 4 CRCT Preparation 10. Kaolin is a white claystone that is composed of kaolinite and other minerals. Over 8 million tons of kaolin are mined in Georgia each year. Kaolin is used as a coating on glossy paper. It is also used in the production of ceramics, paints, plastics, and rubber. What type of rock is kaolin? How is kaolin rock formed?

21 < BackNext >PreviewMain Chapter 4 CRCT Preparation 10. Answer - Full-credit answers should include the following points: Kaolin is a clastic sedimentary rock. Kaolin is formed when kaolinite and other mineral particles become cemented together. The particles in kaolin were cemented together by a mineral such as calcite or quartz.

22 < BackNext >PreviewMain Chapter 4 CRCT Preparation 11. Tim is studying the geology of Georgia. He discovers that the Lexington Oglesby Blue Granite Belt lies beneath Elberton County in Georgia. This deposit contains Elberton granite, also called “Georgia Gray” because of its color. The stone consists of coarse light gray and dark gray grains. Elberton granite can be seen all over the United States, in buildings, monuments, and gravestones. What was the process that formed Elberton granite? What can you infer about the properties of this stone from its uses?

23 < BackNext >PreviewMain Chapter 4 CRCT Preparation 11. Answer - Full-credit answers should include the following points: Elberton granite is an igneous rock, which formed when melted magma cooled. It was most likely formed by an intrusion of magma, which cooled slowly below Earth’s surface to create the coarse-grained rock. Because the rock is used for buildings and monuments, it must be strong and durable outdoors.
