Near the bottom of the rock layers
c)
In the middle of the rock layers
d)
Somewhat near the surface
3.
Which rock layer in the diagram seems to be the oldest?
a)
F
b)

c)
B
d)

4.
In this rock layer diagram there are two unconformities, a fault at E and an intrusion at D. Which unconformity occurred first? How do you know?
a)
Intrusion D occurred first because the instrusion has been moved by the fault.
b)
The fault occurred first because it has moved the intrusion D.

Sea levels use to be much lower
c)
Plate boundary movement is the only correct explanation for marine fossils in strange places
