2. 1. What properties do scientists observe when studying rocks? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Geologists observe the rock’s mineral composition, color, and texture.

3. 2. What are rocks made of? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Mixtures of minerals and other materials

4. 3. Explain how color helps identify a rocks mineral composition. CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Color gives clues to mineral composition, but is not enough alone to identify rocks.

5. 4. What gives rocks texture? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Particles of minerals or other rock are the grains that give rocks texture.

6. 5. How do scientists describe texture (3)? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Size, Shape, and Pattern

7. 6. Explain grain size, shape, and pattern. CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Size: fine, coarse, none Shape: rounded, jagged Pattern: banded, non-banded

8. 7. Three types of rock are…? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS Igneous, metamorphic, sedimentary

9. 8. Classified according to…? CHAPTER 6, LESSON 2: CLASSIFYING ROCKS How they were formed.
