The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
Then you would be able to observe the next to the youngest rock layer.
The "youngest" (newest) sedimentary rocks are a few million years old, those that underwent rapid compaction in the shortest lithification process.
The Mid-Atlantic Ridge is neither Continental rock or indeed the oldest rock on the planet. The rock in the ridge is commonly the youngest, or of the youngest, on the planet, as it was formed most recently, and is oceanic, not continental, crustal rock.
