Law of Superposition

Which of the following orders the rock layers accurately from youngest to oldest?

• 1, 2, 3, 4, 5
• 5, 4, 3, 2, 1
• 2, 3, 4, 5, 1
• 1, 2, 3, 5, 4

Which of the following is the oldest?

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

What is the oldest layer in the outcrop?

• B
• C
• D
• E

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

• fault
• intrusion
• inclusion
• unconformity

_{Which rock layer in the diagram seems to be the oldest?}

• F
• E
• B
• A

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

Superposition means that in an undisturbed sequence of sedimentary rocks, which of the following is true?

• The oldest rocks are on top.
• The youngest rocks are in the middle.
• The youngest rocks are on the top.
• There is no way to know which layers are older.

The law of superposition states:

• each rock layer is older than the one above it
• each rock layer is younger than the one above it
• each rock layer is the same as the one above it
