Chapter 11 Summary and Review: Questions 1-25 Alex Chen Galloway/P5 May 14, 2003 1: A (i) rock is a naturally formed solid material usually made of minerals. 2: The (l) texture determines the size and shape of the mineral grains in a rock. 3: (c) Compaction is the process transforming sediment into rock as a result of pressure. 4: (g) Metamorphism is the changing of one type of rock into another by great heat, great pressure, and chemical change. 5: A rock is (e) foliated if it involves having minerals arranged in parallel layers or bands. 6: (a) Cementation is the process by which sediments are joined together to form rock. 7: The (k) structure determines the arrangement of minerals in a rock. 8: (b) Clastic rock is a type of sedimentary rock consisting of broken fragments of rock and minerals. 9: (j) Sediments are small bits of matter deposited by rain, water, or ice. 10: (d) Extrusive rock is igneous rock formed from lava. 11: The main difference between rocks and minerals is that rocks (b) are usually mixtures so their composition is not always the same. 12: Rocks formed by the cooling and hardening of magma and lava are called (a) igneous. 13: A common feature of sedimentary rocks is (c) fossils. 14: A rock is hard, crystalline, and dense. Its crystals are large and arranged in alternating light and dark colored layers. It contains no fossils. The rock is probably (c) foliated metamorphic rock. 15:An example of an igneous rock is (a) granite. 16: A clastic sedimentary rock formed by the cementation of pebbles, gravel, and sand is (b) sandstone. 17: An example of a metamorphic rock formed from granite is (a) gneiss. 18: A sedimentary rock formed from clay-sized sediments is (c) shale. 19: The never-ending changing of one rock type to another is (b) the rock cycle. 20: Limestone, coquina, and chalk are all (a) sedimentary rocks. 21: The three types of sedimentary rocks are clastic, chemical, and organic rocks. 22: Metamorphic rock forms when rock is changed due to heat and/or pressure (Rock is changed primarily due to heat in contact metamorphism). 23: Two ways metamorphism can occur are through regional metamorphism and contact metamorphism. 24: The type of rock formed when magma and lava harden is igneous rock. 25: Rocks undergo continuous changes; which results in the rock cycle.
