Foldables Rocks and Minerals Make the following Foldable to compare and contrast the characteristics of rocks and minerals.
Foldables Fold one sheet of paper lengthwise.
Foldables Fold into thirds.
Foldables Unfold and draw overlapping ovals. Cut the top sheet along the folds.
Foldables Label the ovals as shown.
Foldables Construct a Venn Diagram As you read the chapter, list the characteristics unique to rocks under the left tab, those unique to minerals under the right tab, those characteristics common to both under the middle tab.

Reviewing Main Ideas 1 Minerals – Earth’s Jewels • Minerals are inorganic solid materials found in nature. They have a definite chemical makeup, and an orderly arrangement of atoms. Rocks are combinations of two or more minerals. • Physical properties of minerals are observed to help identify them. • Gems are minerals that are rare and beautiful. • Ores of useful materials must be mined and processed to extract the desired substance.
Reviewing Main Ideas 2 Igneous and Sedimentary Rocks • Igneous rocks form when melted rock material from inside Earth cools and hardens. Extrusive rocks form above Earth’s surface. Intrusive rocks solidify beneath the surface. • Sedimentary rocks formed from mineral or rock fragments are called detrital rocks. • Rocks formed as mineral-rich water evaporates are examples of chemical rocks. Rocks composed of fossils or plant remains are organic rocks.
Reviewing Main Ideas 3 Metamorphic Rocks and the Rock Cycle • Metamorphic rocks form as a result of changing temperature, pressure, and fluid conditions inside Earth. • The rock cycle describes how all rocks are subject to constant change.
Chapter Review Question 1 Explain how sediment becomes sedimentary rock.
Chapter Review Answer Sediment is pieces of broken rock, shells, mineral grains, and other materials that are deposited deep in the ocean, where it piles up over time. As more layers of sediment pile up, the layers underneath are compacted. Water flows through the sediment and acts like glue. It is the compacted layers that eventually become sedimentary rock.
Chapter Review Question 2 Which changes metamorphic rock into sediment? A. compaction and cementation B. heat and pressure C. melting D. weathering and erosion
Chapter Review Answer The answer is D. Over time, weathering and erosion change metamorphic rock back into sediment.
Chapter Review Question 3 List the different properties that are used to identify minerals. Answer Crystal, cleavage and fracture, color, streak and luster, hardness, and specific gravity are used to identify minerals.
Chapter Review Question 4 Rank the four minerals from softest to hardest.
Chapter Review Answer The correct order is: talc, gypsum, fluorite, and quartz.
Chapter Review Question 5 Explain why intrusive igneous rocks have large, visible crystals.
Chapter Review Answer Intrusive igneous rocks are formed by magma that is forced upward toward Earth’s surface, but never reaches it. The hot magma sits under the surface and cools very slowly. The cooling is so slow that the minerals in magma have time to form large crystals.
Standardized Test Practice Question 1 When a mineral splits into pieces with smooth, regular planes, it is said to have _______. A. cleavage B. crystals C. luster D. specific gravity
Standardized Test Practice Answer The answer is A. Cleavage is a way that rock can break. When rocks break with smooth, regular planes, they have cleavage. Rocks that break into pieces with jagged, rough edges, fracture.
