Foldables

Rocks and Minerals

Make the following Foldable to compare and contrast the characteristics of rocks and minerals.

slide31

Foldables

Fold one sheet of paper lengthwise.

slide32

Foldables

Fold into thirds.

slide33

Foldables

Unfold and draw overlapping ovals. Cut the top sheet along the folds.

slide34

Foldables

Label the ovals as shown.

slide35

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.
slide38

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.

PS 2.2g

slide41

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.

slide42

Chapter Review

Question 2

Which changes metamorphic rock into sediment?

A. compaction and cementation

B. heat and pressure

C. melting

D. weathering and erosion

PS 2.2g

slide43

Chapter Review

Answer

The answer is D. Over time, weathering and erosion change metamorphic rock back into sediment.

slide44

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.

PS 2.1e

slide45

Chapter Review

Question 4

Rank the four minerals from softest to hardest.

PS 2.1e

slide46

Chapter Review

Answer

The correct order is: talc, gypsum, fluorite, and quartz.

slide47

Chapter Review

Question 5

Explain why intrusive igneous rocks have large, visible crystals.

PS 2.2g

slide48

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

PS 2.1e

slide50

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.

Question 2

What type of rock is formed after a geyser erupts?

A. chemical rocks

B. detrital rocks

C. organic rocks

D. volcanic rocks

PS 2.2h

slide52

Standardized Test Practice

Answer

The answer is A. When a geyser erupts, mineral-rich water evaporates. The minerals are left behind and they eventually form chemical rocks.

slide53

Standardized Test Practice

Question 3

Where do extrusive igneous rocks form?

A. Earth’s surface

B. inside Earth

C. water

D. space

PS 2.2g

slide54

Standardized Test Practice

Answer

The answer is A. Extrusive igneous rocks form when melted rock material cools on Earth’s surface.

Question 4

Which is most abundant in Earth’s crust?

A. calcite

B. feldspar

C. halite

D. silica

PS 2.1c

slide56

Question 5

Which is a mineral sold for profit?

A. gem

B. granite

C. rock

D. ore

PS 2.1e

slide58

Standardized Test Practice

Answer

The correct answer is D. A mineral that contains a useful substance that can be sold for profit is called an ore.
