Mineral and Rock Review
Write answers on separate sheet of paper and staple to review sheet.
Use your notes, your foldable and chapters 14 & 15 to help you answer the questions & study for the test.
Be able to explain the rock cycle, read a diagram/chart/graph/ or table, and identify rocks based on
their characteristics (intrusive igneous, extrusive igneous, metamorphic, & sedimentary)
Minerals
What are the characteristics a rock must have to be defined as a mineral?
2.
Explain how ice could be considered a mineral?
3.
What is the most common group of rock forming minerals?
4.
What is the second most common group?

Identify and explain the properties used to identify minerals.
7.
Explain what density is and how it can be measured.
8.
What is the hardest mineral on the Mohs scale?

What are four other properties that only a few minerals have?
10. What are the 5 ways minerals can form?
11. What is ore?
Rocks
12. What is a rock and how is it different from a mineral?
13. Give an example of a rock with only one mineral.
14. Give an example of a rock with no minerals.
15. What is the rock cycle?
16. Where does the rock cycle begin and end? (trick question!)
17. What percentage of the surface of the crust is sedimentary rock?

25. Give two examples of an extrusive igneous rock.
26. How can you tell an intrusive igneous rock from an extrusive igneous rock?
27. How is the texture of an igneous rock determined?
28. What is the main element used to determine the composition of an igneous rock?
29. If an igneous rock has a high level of silica is it dark or light in color?

What is sediment?
Name three ways sedimentary rocks are formed.
What kind of rock can fossils be found in?
When heat and pressure changes an existing rock into another rock what type
of rock is formed (or reformed)?
What are the 2 different types of metamorphism?
Give the series of metamorphic rocks that can be formed as shale, a
sedimentary rock, is changed by continuous heat and pressure.
When atoms join together differently new bonds form, this is called
recrystallization. What are the two main things that can happen to a rock’s
minerals when recrystallization happens?
What happens to the minerals when foliation occurs?
How can you tell if a metamorphic rock is foliated?
Why do some rocks not show foliation?

Put in the correct order
A. burial
B. compaction
C. cementation
D. sediment is deposited somewhere
44.
What happens when gneiss is melted? Explain your answer(s) using a complete
scntence(s).
A. It becomes magma.
B. It becomes sediment.
