The statement that the oldest layer will be at the bottom in an undisturbed sequence of rock layers is called the Principle of ....

• Inclusions
• Unconformities
• Cross-Cutting Relationships
• Superposition

The Principle of Cross-Cutting Relationships states that an igneous intrusion is 

• always younger than the layers it cuts across
• always older than the layers it cuts across
• the same age as the rock it melted
• none of the answers are correct

Relative age dating is used to determine the...

• actual age of an event
• length of time between two events
• age of one event in comparison with other events
• rate at which a gologic process occurs

Which of the following correctly lists the layers in order from oldest to youngest?

• A, B, C, D, E
• E, B, C, D, A
• E, D, C, B, A
• C, B, A, D, E

The rock formation labeled "P" is a(n)...

An archaeologist made the following diagram of a dig site. What can be said about the pottery as compared to the skull found in the site?

• The rock layer with the pottery is more recent than the rock layer with the skull.
• The rock layer with the skull is more recent than the rock layer with the pottery.
• The rock layer with the skull is approximately the same age as the rock layer with the pottery.
• The rock layer with the skull has an absolute date of 17,000 years.

The age of a rock compared to the ages of other rocks is the rock's

• absolute age
• geologic age
• sedimentary age
• relative age

The number of years that have passed since the rock formed is the rock's

• relative age
• law of superposition
• absolute age
