  1. theBIGidea CHAPTER OUTLINE CHAPTER RESOURCES CHAPTER NEW CHAPTER Rocks Rocks change into other rocks over time. 3.1 The rock cycle shows how rocks change. 3.2 Igneous rocks form from molten rock. 3.3 Sedimentary rocks form from earlier rocks. 3.4 Metamorphic rocks form as existing rocks change.

  2. sediment metamorphic igneous sedimentary magma 3.1 The rock cycle shows how rocks change. Processes at Earth's surface and heat within Earth cause rocks to change into other types of rocks. rock rock cycle igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES SECTION OUTLINE

  3. VISUALIZATION CLASSZONE.COM Explore how rocks form and change. 3.1 The rock cycle shows how rocks change. Processes at Earth's surface and heat within Earth cause rocks to change into other types of rocks. rock rock cycle igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES SECTION OUTLINE

  4. igneous 3.2 Igneous rocks form from molten rock. As molten rock cools, minerals crystallize and form igneous rocks. intrusive igneous rock extrusive igneous rock CHAPTER RESOURCES SECTION OUTLINE

  5. Extrusive igneous rocks cool quickly at Earth's surface. Intrusive igneous rocks cool slowly within Earth. VISUALIZATION CLASSZONE.COM Explore an animation showing how crystals form as molten rock cools. 3.2 Igneous rocks form from molten rock. As molten rock cools, minerals crystallize and form igneous rocks. intrusive igneous rock extrusive igneous rock CHAPTER RESOURCES SECTION OUTLINE

  6. 3.3 Sedimentary rocks form from earlier rocks. Layers of sedimentary rocks form as sediment • sediments are pressed or cemented together CHAPTER RESOURCES SECTION OUTLINE

  7. 3.3 Sedimentary rocks form from earlier rocks. Layers of sedimentary rocks form as sediment • sediments are pressed or cemented together • dissolved minerals re-form as water evaporates CHAPTER RESOURCES SECTION OUTLINE

  8. schist shale heat and pressure 3.4 Metamorphic rocks form as existing rocks change. Metamorphic rocks form as the structure of the parent rocks change and as their minerals recrystallize. metamorphism recrystallization foliation CHAPTER RESOURCES SECTION OUTLINE

  9. 3.1 The rock cycle shows how rocks change. I. The rock cycle shows how rocks change. rock • A. Most rocks are made of minerals. rock cycle • B. Our world is built of rocks. igneous rock • C. Rocks change as they move through the rock cycle. sedimentary rock • 1. Rock Types metamorphic rock • 2. Rocks in the Crust CHAPTER RESOURCES KEY CONCEPT SUMMARY

  10. 3.2 Igneous rocks form from molten rock. II. Igneous rocks form from molten rock. intrusive igneous rock A. Magma and lava form different types of igneous rocks. extrusive igneous rock • 1. Origin of Igneous Rocks • 2. Textures of Igneous Rocks • 3. Composition of Igneous Rocks • B. Igneous rocks make long-lasting landforms. • 1. Intrusive Rock Formations • 2. Extrusive Rock Formations CHAPTER RESOURCES KEY CONCEPT SUMMARY

  11. 3.3 Sedimentary rocks form from earlier rocks. III. Sedimentary rocks form from earlier rocks. sediment • A. Some rocks form from rock particles. • 1. Forming and Transporting Rock Particles • 2. Forming Loose Sediment into Rocks • B. Some rocks form from plants or shells. • 1. Coal • 2. Limestone • C. Some rocks form when dissolved minerals • re-form from water. CHAPTER RESOURCES • D. Sedimentary rocks show the action of wind and water. KEY CONCEPT SUMMARY

  12. 3.4 Metamorphic rocks form as existing rocks change. IV. Metamorphic rocks form as existing rocks change. metamorphism • A. Heat and pressure change rocks. recrystallization • B. Metamorphic changes occur over large and small areas. foliation • 1. Change over Large Areas • 2. Change over Small Areas • C. Most metamorphic rocks develop bands of minerals. • 1. Foliated Rocks • 2. Nonfoliated Rocks CHAPTER RESOURCES KEY CONCEPT SUMMARY
