  1. Chapter 8 Section 2Igneous and sedimentary rocks Mr. Perez Chapter 8 Section 3Metamorphic rocks and rock cycle

  2. Section 2 Vocabulary • 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

  3. Igneous Rock Details

  4. Organize igneous rocks

  5. Classify Sedimentary rocks

  6. Section 3 Vocabulary • Pressure- force applied over a given area • Metamorphic rock- new rocks that form when existing rocks are heated or squeezed but 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

  7. Summarize metamorphic Rocks

  8. Draw metamorphic rocks

  9. DRAW Metamorphic rocks • Foliated rocks include: slate gneiss phyllite schist

  10. Draw Metamorphic Rocks • Nonfoliated rocks include: quartzite soapstone marble
