&
Lesson 2.2: Rocks and Weathering

2. This type of rock forms when molten material cools.
What is igneous rock?

3. These are the five characteristics of a mineral.
What are:
Naturally occurring
Inorganic
Solid
Crystal shape
Definite chemical composition

4. This process slowly changes rocks from one kind to another.
What is the rock cycle?

5. What is mechanical weathering?
Animals that burrow in the ground help contribute to this type of weathering.
What is mechanical weathering?

6. When water freezes in a rock it expands causing the crack to widen.
What is ice wedging?

7. This picture is an example of what type of mining?
What is an
open-pit mine?

8. What is sedimentary rock?
This type of rock forms through the process of compaction and cementation.
What is sedimentary rock?

9. Rain combined with pollutants help to form this type of rapid chemical weathering.
What is acid rain?

10. This mineral characteristic is made up of particles that line up in a pattern that repeats over and over again.
What is crystal shape?

11. What is a nonrenewable resource?
Rocks are considered to be this because they take millions of years to be replaced.
What is a nonrenewable resource?

12. Rocks that are made up of tiny, connected air spaces are considered this.
What is permeable?

13. To remove ore deposits that occur in veins, miners build this type of mine.
What is a shaft mine.

14. Which of the following is NOT one of the possible stages in the rock cycle?
Erosion
Volcanic activity
Melting
Smelting
What is smelting?

15. This type of weathering occurs more rapidly in hot, wet climates.
What is chemical weathering?

16. The movement of rock particles by ice, wind, water, or gravity is known as this.
What is erosion?

17. This type of igneous rock is commonly used for building materials.
What is granite?

18. What is metamorphic rock?
Intense heat and pressure can change the minerals in rock into this type of rock.
What is metamorphic rock?

19. What are possible uses of rocks?
Floors, kitchen counters, walls of buildings, roofing, cement and steel are all examples of this.
What are possible uses of rocks?

20. This mineral characteristic did not form from materials that were once living.
What is inorganic?

21. The type of mining where soil is scraped away to expose ore.
What is a strip mine?

22. The grinding away of rock by rock particles carried by water, wind, or gravity is known as this.
What is abrasion?

23. The End.
How did you do?
