3. 2 CHAPTER HOME KEY CONCEPT Igneous rocks form from molten rock. As molten rock cools, minerals crystallize and form igneous rocks. Extrusive igneous rocks cool quickly at Earth's surface. VOCABULARY intrusive igneous rock extrusive igneous rock Intrusive igneous rocks cool slowly within Earth. VISUALIZATION CLASSZONE. COM Explore an animation showing how crystals form as molten rock cools. CHAPTER RESOURCES SECTION OUTLINE

3. 3 CHAPTER HOME KEY CONCEPT Sedimentary rocks form from earlier rocks. Layers of sedimentary rocks form as VOCABULARY sediment • sediments are pressed or cemented together • dissolved minerals re-form as water evaporates CHAPTER RESOURCES SECTION OUTLINE

3. 4 CHAPTER HOME KEY CONCEPT Metamorphic rocks form as existing rocks change. Metamorphic

3. 4 CHAPTER HOME KEY CONCEPT Metamorphic rocks form as existing rocks change. Metamorphic rocks form as the structure of the parent rocks change and as their minerals recrystallize. VOCABULARY metamorphism recrystallization foliation heat and pressure shale schist CHAPTER RESOURCES SECTION OUTLINE
