Define the three types of rocks.
Describe how igneous, sedimentary, and metamorphic rocks form.
Diagram the rock cycle.
Identify igneous, sedimentary, and metamorphic rocks and the various
properties of each.
7. Identify the mineral composition in igneous, sedimentary, and metamorphic

Igneous
8. Describe the difference between extrusive (volcanic) and intrusive
(plutonic) igneous rocks.
9. Describe the difference between magma and lava.
10. Identify the factors that control melting of rocks.

(fine-grained) igneous rock textures.
13. Describe the differences between felsic and mafic igneous rocks.
Sedimentary
14. Describe the difference between clastic and non-clastic sedimentary rocks
15. Identify the depositional environments of various sedimentary rocks.
16. Identify a well-sorted and poorly sorted sedimentary rock.
17. Explain how the grains in a sedimentary rock changes as it moves further
from its source.
Metamorphic
18. Describe the differences between foliated and non-foliated metamorphic
rocks.
