- Know the composition of the major mineral groups
Rocks
- What is meant by the rock cycle?
- Igneous rocks

- what is the source for magma; what are the mechanisms that trigger rock to melt at
depth?
- what are the different magma types and how do they compare in composition?

melting, assimilation, etc.)

- Metamorphic rocks
- know what causes rocks to metamorphose
- know the different things that can happen to a rock when it undergoes metamorphism
(i.e. change in texture, change in minerals)
- know how metamorphic rocks are classified

- know what is meant by metamorphic grade
- know the different types of metamorphism (i.e. contact, regional, etc.)
Plate Tectonics
- core vs. mantle vs. crust (dimensions, properties, and composition)
- lithosphere vs. asthenosphere vs. continental crust vs. oceanic crust (dimensions, properties, and
composition)
- know the concepts of the continental drift hypothesis

- know the characteristics of the three major plate boundaries: convergent, divergent,
and transform
- know the characteristics of hot spots and rift systems
