Identifying Rock Layers

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
