Metamorphic Rocks Section 3 of chapter 2
Table of Contents How science works pg 1-2 Scientific Method pg 3-10 Science engineering and tech. pg 9-12 Chapter 1 review pg 13 Mineral Earth’s Jewels pg 15-20 Section 1 review pg 22 Igneous and Sedimentary pg 23-28 Metamorphic Rock pg29-32 Rock Cycle pg 33-34
Essential Question • Describe the conditions needed for metamorphic rocks to form. • Explain how all rocks are linked by the rock cycle.
Metamorphic Rocks pg 30 • How do metamorphic rocks form? • Metamorphic rocks are formed from existing rocks. When the existing rocks are exposed to heat and pressure, but are not melted.
Metamorphic rocks pg 30 • What does the word metamorphic mean? • What Earth processes could generate the pressures needed for metamorphic changes? • It means to change form. • Mountain building, movement along a fault, burial beneath other rock layers.
Metamorphic Rocks pg 32 • What can metamorphic rocks change from? • What is a physical characteristic that can help classify metamorphic rocks? • Metamorphic rocks can change from igneous, sedimentary, or from metamorphic rocks. • The texture of a metamorphic rock is what helps to set them apart. Metamorphic rocks either foliated or nonfoliated.
Metamorphic Rocks pg 32 • What does it mean if a rock is foliated? • If a rock is foliated the rock has visible layers or elongated grains of minerals. These minerals in the rock have been heated and squeezed into pararllel layers
Metamorphic Rocks pg 32 • What does it mean if a metamorphic rock is nonfoliated? • If a metamorphic rock is nonfoliated the rock does not have distinct layers or bands.
Rock Cycle pg 34 • What is the rock cycle? • The rock cycle is a model used to describe how different kinds of rock are related to another.
Section 3 review • Identify two factors that can produce metamorphic rocks? • List examples of foliated and nonfoliated rocks. Explain the difference between the two types of metamorphic rocks. • Explain Igneous and metamorphic rocks can form at high temperatures and pressures, What is the difference between the two types of rock? • Explain how the rock cycle works? • Pretend you are a piece of granite. Describe your journey as you move through the rock cycle as you change into an Igneous rock then to a sedimentary rock, then back to a metamorphic rock.
