Earths history and Rock Layers 2

The Law of Superposition helps scientists to determine what?

• The absolute age of rock layers
• The age of fossils
• The relative age of rock layers
• the super powers of rocks

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface

Which type of dating method can be used on rock layers by applying the Law of Superposition?

• relative dating
• absolute dating
• radioactive dating
• radiometric dating

Which of the following is the oldest?

• Layer L
• Intrusion D
• Intrusion H
• Layer E

What is the youngest layer in the outcrop?

• A
• B
• C
• D

Letter "F" is a....

• inclusion
• intrusion
• fault
• unconformity 

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?

• Intrusion D occurred first because the instrusion has been moved by the fault.
• The fault occurred first because it has moved the intrusion D.
• Intrusion D occurred first because it can be seen in all of the rock layers.
• Fault E occurred first because it is a normal fault.

To be considered an index fossil, it had to have lived for a relatively short period of time.

• True
• False

The Principle of Superposition states that the oldest layer of rock is located at the/a...

• Bottom
• Middle
• Random Location

• Jellyfish
• Shark
• Lizards
• Horses
