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

2 VOCABULARY KEY CONCEPT CHAPTER HOME 3.1 SECTION OUTLINE SECTION OUTLINE rock cycle rock 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. sediment magma sedimentary metamorphic igneous igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

4 VOCABULARY KEY CONCEPT CHAPTER HOME A naturally formed solid that is usually made up of one or more types of minerals. rock 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

5 VOCABULARY KEY CONCEPT CHAPTER HOME The set of natural, repeating processes that form, change, break down, and re-form rocks. rock cycle 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

6 VOCABULARY KEY CONCEPT CHAPTER HOME Rock that forms as molten rock cools and becomes solid. igneous rock 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

7 VOCABULARY KEY CONCEPT CHAPTER HOME Rock formed as pieces of older rocks and other loose materials get pressed or cemented together or as dissolved minerals re-form and build up in layers. sedimentary rock 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

8 VOCABULARY KEY CONCEPT CHAPTER HOME Rock formed as heat or pressure causes existing rock to change in structure, texture, or mineral composition. metamorphic rock 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

9 VOCABULARY KEY CONCEPT CHAPTER HOME Igneous rocks form from molten rock. 3.2 SECTION OUTLINE SECTION OUTLINE extrusive igneous rock intrusive igneous rock As molten rock cools, minerals crystallize and form igneous rocks. igneous CHAPTER RESOURCES CHAPTER RESOURCES

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

11 VOCABULARY KEY CONCEPT CHAPTER HOME Igneous rock that forms as magma cools below Earth’s surface. intrusive igneous rock 3.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Igneous rocks form from molten rock. extrusive igneous rock intrusive igneous rock CHAPTER RESOURCES CHAPTER RESOURCES

12 VOCABULARY KEY CONCEPT CHAPTER HOME Igneous rock that forms as lava cools on Earth’s surface. extrusive igneous rock 3.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Igneous rocks form from molten rock. extrusive igneous rock intrusive igneous rock CHAPTER RESOURCES CHAPTER RESOURCES

13 VOCABULARY KEY CONCEPT CHAPTER HOME 3.3 SECTION OUTLINE SECTION OUTLINE Sedimentary rocks form from earlier rocks. sediment Layers of sedimentary rocks form as sediments are pressed or cemented together CHAPTER RESOURCES CHAPTER RESOURCES

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

15 VOCABULARY KEY CONCEPT CHAPTER HOME Solid materials such as rock fragments, plant and animal remains, or minerals that are carried by water or by air and that settle on the bottom of a body of water or on the ground. sediment 3.3 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Sedimentary rocks form from earlier rocks. sediment CHAPTER RESOURCES CHAPTER RESOURCES

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

17 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which a rock’s structure or mineral composition is changed by pressure or heat. metamorphism 3.4 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Metamorphic rocks form as existing rocks change. recrystallization metamorphism foliation CHAPTER RESOURCES CHAPTER RESOURCES

18 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which bonds between atoms in minerals break and re-form in new ways during metamorphism. recrystallization 3.4 Metamorphic rocks form as existing rocks change. recrystallization metamorphism foliation KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY CHAPTER RESOURCES CHAPTER RESOURCES

19 VOCABULARY KEY CONCEPT CHAPTER HOME The arrangement of minerals within rocks into flat or wavy parallel bands; a characteristic of most metamorphic rocks. foliation 3.4 Metamorphic rocks form as existing rocks change. recrystallization metamorphism foliation KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY CHAPTER RESOURCES CHAPTER RESOURCES

Our world is built of rocks. 3.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY The rock cycle shows how rocks change. C. Rocks change as they move through the rock cycle. 2. Rocks in the Crust 1. Rock Types rock cycle rock igneous rock sedimentary rock metamorphic rock CHAPTER RESOURCES CHAPTER RESOURCES

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

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