1 Mr. Perez CHAPTER 8 SECTION 2 IGNEOUS AND SEDIMENTARY ROCKS CHAPTER 8 SECTION 3 METAMORPHIC ROCKS AND ROCK CYCLE

2  Lava- molten rock material that exists at or above Earth’s surface  Igneous rock- rock formed when melted rock material from inside Earth cools  Extrusive- melted rock material cools on Earth’s surface  Intrusive- melted rock materials cools below Earth’s surface  Sedimentary rock- sediment collected in layers and compacted together SECTION 2 VOCABULARY

3 Igneous Rocks TypeForm from molten rock called Have cooling rate that is Have crystal size that is ExtrusiveLavaFastSmall IntrusiveMagmaSlowLarge IGNEOUS ROCK DETAILS

4

5 Igneous Rocks can be Light colored Have High silica content Are called Granitic Dark colored Have Low silica content Are called Basaltic ORGANIZE IGNEOUS ROCKS

7 DetritalChemicalOrganic Form fromMade of grains of minerals or other rocks Dissolved mineral in seawater, geysers, hot springs, or salty lakes Living matter that has died How formMoved and been deposited in layers by water, ice, gravity or wind Evaporation or other chemical processes Piled up and compressed into rock Where formLand or waterWaterLand or ocean ExamplesSandstone, Shale, Conglomerate, Siltstone HaliteChalk, coal, limestone CLASSIFY SEDIMENTARY ROCKS

8  Pressure- force applied over a given area  Metamorphic rock- new rocks that form when existing rocks are heated or squeezed by not melted  Foliated- rocks that have visible layers or elongated grains of mineral  Nonfoliated- rocks that do not have distinct layers or bands of minerals  Rock cycle- cycle that describes how different kinds of rock are related to one another and how rocks change from one type to another SECTION 3 VOCABULARY

9 Conditions of Metamorphic Rock Formation TemperatureHigh PressureHigh TimeMillions of years SUMMARIZE METAMORPHIC ROCKS

10

11 DRAW METAMORPHIC ROCKS

12  Foliated rocks include: DRAW METAMORPHIC ROCKS slate gneiss schist phyllite

13  Nonfoliated rocks include: DRAW METAMORPHIC ROCKS quartzite marble soapstone

14

15  ROCK CYCLE INTERACTIVE

16  Chapter 8 vocabulary quiz on A: 12/10 or B:12/11  Band kids will take it during the next class period  Mineral Mania Mini Project due A: 12/10 or B: 12/11  Bring in old crayons, aluminum foil, wax paper and pencil sharpeners A: 12/10 or B: 12/11  Rock cycle quiz on A: 12/12 or B: 12/13  Study the diagram on p  Be able to describe it in words and fill in the words on the arrows REMEMBER!
