58. Section Check 2 Answer The correct answer is A. Igneous rock forms when melted rock, called magma, cools. NC: 3.04
59. Section Check 2 Question 2 What determines the color of igneous rock? Answer The chemicals in the melted rock determine the color of igneous rock. NC: 3.04

71. Section Check 3 Question 1 What type of rock results when an existing rock changes form? A. igneous rock B. metamorphic rock C. a mineral D. sedimentary rock NC: 3.04
72. Section Check 3 Answer The answer is B. A metamorphic rock is formed when an existing rock is heated by Earth’s temperature or squeezed by intense pressure. NC: 3.04
73. Section Check 3 Question 2 Compare and contrast the two groups of metamorphic rocks. Answer Foliated rocks have many layers. Nonfoliated rocks do not have layers and the individual mineral grains can be difficult to see. NC: 3.04
74. Section Check 3 Question 3 Would you expect to find a well-preserved artifact in a metamorphic rock such as quartzite? Explain. NC: 3.04
75. Section Check 3 Answer No; quartzite is an example of a nonfoliated metamorphic rock. These rocks do not have distinct layers. Quartzite forms when quartz sand grains recrystallize during intense heating and pressure. An artifact would get destroyed during this process. NC: 3.04
