25-26 FCHS Earth Systems: U7, Topic 2 Quiz

How does relative age dating differ from absolute age dating?

• Relative age dating provides a specific age in years.

• Relative age dating estimates the order of events without exact dates.

• Relative age dating uses radiometric techniques.

• Relative age dating measures the decay of isotopes.

How can relative age dating be used to interpret the sequence of geological events in a region?

• By providing exact dates for each event.

• By determining the order of events based on the relationships between rock layers and features.

• By using radiometric techniques.

• By measuring the decay of isotopes.

• Younger layers are found above older layers.

• All layers are the same age.

• Layers are deposited vertically.

According to the Principle of Cross-Cutting, what is the age relationship between a geologic feature and cross-cuts?

• The feature that cuts through another is older.

• The feature that is cut is older.

• Both features are the same age.

• The features are unrelated in age.

Which principle is shown in the picture?

• Intrusions

• Faunal Succession

• Original Horizontality

• Lateral Continuity

How does the Principle of Superposition help in determining the relative age of rock layers?

• By identifying the mineral composition of each layer.

• By determining the sequence of deposition.

• By measuring the thickness of each layer.

• By analyzing the color of each layer.

How can Original Horizontality be used to identify geological events?

• It shows that all layers are deposited at the same time.

• It indicates that any tilting or folding occurred after deposition.

• It suggests that layers are deposited in a circular pattern.

• It proves that layers are deposited vertically.

What information can unconformities provide about past geological processes?

• They indicate continuous deposition of sediments.

• They provide evidence of erosion or non-deposition, indicating changes in environmental conditions.

• They show that all rock layers are the same age.

• They suggest that all rock layers are horizontal.
