Directions: Answer the following questions.
1. How do rocks and minerals differ?
2. What is the rock cycle?
3. What are the two groups of igneous rocks are classified as? Explain each group.
4. What is partial melting? Explain how partial melting affects igneous rock formation?
5. How can a metamorphic rock become an igneous rock?
Directions: For each statement, write true or false.
9.The temperature in Earth’s crust decreases with depth.
10.Sedimentary rocks form from rock and mineral fragments, and metamorphic
rocks form from existing rock.
11. Magmas are classified as basaltic, andesitic, or rhyolitic.
12.Molten rock inside Earth’s crust is called lava.
13.Basaltic magma has the highest silica content.
14.Magma that has a low silica content is called rhyolitic.
15. Lithification is a chemical process that transforms sediments into sedimentary
rock.
16. Bedding is the primary feature of sedimentary rocks.
17. Clastic means broken.
18. Unfoliated rocks have many layers and bands.
Directions: Use each of the terms below just once to complete the passage.
cementation
chemical weathering
clastic sediments
deposition
lithification
physical weathering
sedimentary rock
sorted deposits
sediment
unsorted deposits
16.
consists of solid material that has been deposited on Earth’s surface by wind,
water, ice, gravity, or chemical precipitation.
17. Glaciers and landslides tend to create
in which sediments of different sizes are
mixed together.
18. During
, the minerals in a rock are dissolved or otherwise chemically
changed.
19.The process by which mineral growth binds sediment grains together into solid rock is
.
20.Weathering produces
, which are rock and mineral fragments.
21.When sediments become cemented together, they form
22. As a result of
.
, sediments are laid down on the ground or on the bottom of
bodies of water.
23.The physical and chemical process called
transforms sediments into
sedimentary rocks.
24. During
, minerals remain unchanged, and rock fragments simply break off of
the solid rock along fractures or grain boundaries.
25. Sediments tend to form
when transported by water and wind.
Directions: Match the definition with the correct term.
a. cementation
b. cross-bedding
c. graded bedding
d. clastic
e. porosity
d. foliation
29. Formed as inclined layers of sediment are deposited across a horizontal surface.
30. Particle size becomes heavier and coarser towards the bottom layers
31. Occurs when mineral growth glues sediment grains together.
32. Greek word klastosm, means broken.
33. Layers and bands in rocks.
34. Percent of open spaces between grains in rock
Directions: Compare and contrast each pair of related terms.
35. sedimentary, metamorphic
36. conglomerate, evaporite
37. foliated, nonfoliated
38. regional metamorphism, contact metamorphism, hydrothermal metamorphism
