- 3. Multiple ChoiceWhat 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.
