Focus
Epicenter |
|
|
What is the difference between foliated and non-foliated metamorphic rocks?
|

|
|
List the three major discontinuities and the layers they separate.
|
Lithosphere- crust and the portion of the upper mantle

|
What is the difference between relative geologic time and absolute geologic time?
|
Absolute geologic time places ages on geologic events or units.
Relative time gives qualitative comparisons between events. Example of absolute geologic time: Rock A is 400 millionyears old. Example of relative geologic time: Rock B is younger than Rock A, but older than Rock C. |
