ESS.8.1.1 -Relative Dating

What does the Law of Superposition state about sedimentary rock layers?

• The oldest layer is at the top and the youngest is at the bottom.

• The oldest layer is at the bottom and the youngest is at the top.

• All layers are the same age.

• The age of layers cannot be determined.

If a fault cuts through several layers of sedimentary rock, what can you infer about the age of the fault compared to the layers?

• The fault is older than all the layers

• The fault is younger than the layers it cuts through

• The fault and the layers are the same age

• The fault is older than the top layer only
