What is the law of superposition?

• The age of sedimentary rock not found in the original layers.

• Metamorphic rock is younger than the nearby igneous rock.

• Sedimentary rock in it's original position is older than layers above it.

• Metamorphic rock is older because it was deposited to nearby sedimentary rock.
