Which of the following statements about relative and absolute age dating is correct?
A. Relative age dating places rocks and events in chronological order, but does not provide
information about absolute age.
B. Relative age dating does not provide information about absolute ages, nor does it place rocks
and events in chronological order.
C. Relative age dating provides information about absolute ages, but does not place rocks and
events in chronological order.
D. Relative age dating places rocks and events in chronological order, and can provide
information about absolute age. - Answer A. Relative age dating places rocks and events in
chronological order, but does not provide information about absolute age.
What is the Principle of Original Horizontality?
Metamorphic rocks are close to horizontal when deposited.
Metamorphic rocks are close to horizontal when eroded.
Sedimentary rocks are close to horizontal when deposited.
Sedimentary rocks are close to horizontal when eroded. - Answer Sedimentary rocks are close
to horizontal when deposited.
What is the Principle of Superposition?
A. Within a sequence of rock layers formed at Earth's surface, rock layers lower in the sequence
are older.
B. Within a sequence of rock layers formed at Earth's surface, rock layers higher in the sequence
are older.
C. Within a sequence of rock layers formed at Earth's surface, rock layers in the middle of a
sequence are older. - Answer A. Within a sequence of rock layers formed at Earth's surface,
rock layers lower in the sequence are older.
, B. Geologic features that cut through rocks must form after the rocks that they cut through.
C. Geologic features that cut through rocks must form at roughly the same time as the rocks
that they cut through. - Answer B. Geologic features that cut through rocks must form after
the rocks that they cut through.
series of layers of rocks are cut by two faults. Fault B breaks through to the surface, while Fault
A does not. Which of the following statements about Faults A and B is correct?
A. Fault A is older than Fault B, and Fault A is younger than the surface layer.
B. Fault A is the same age as Fault B, and both are younger than the surface layer.
C. Fault A is younger than Fault B, and Fault A is younger than the surface layer.
D. Fault A is the same age as Fault B, and both are older than the surface layer.
E. Fault A is older than Fault B, and Fault A is older than the surface layer. - Answer E. Fault A is
older than Fault B, and Fault A is older than the surface layer.
Which principle of relative age dating is important for determining the relative age of igneous
rock that has intruded into overlying rock?
A. the Principle of Cross-Cutting Relationships
B. the Principle of Superposition
C. the Principle of Intrusive Relationships
D. the Principle of Original Horizontality - Answer A. the Principle of Cross-Cutting
Relationships
A fault (F) breaks three layers of sedimentary rock (S). An igneous intrusion (I1) has broken
through the bottommost layer of rock. A second igneous intrusion (I2) has moved up the fault
and pooled on top of the uppermost layer of rock. Which event would be considered the
youngest?
A. Faulting of rock along F is the youngest event. We know this because all three layers of
sedimentary rock have been broken.
B. The intrusion of I1 or I2 is the youngest event. Without more information, we cannot know
which igneous rock is youngest.
C. Deposition of the three sedimentary layers, S, is the youngest event. We know this because
the fault underlies the igneous rocks.
