Metaphoric Rocks are the youngest
The youngest rocks in the crust are found on and near active volcanoes, such as those at mid-ocean ridges.

1. If a set of rock layers has been disturbed by movement of tectonic plates, the youngest layer may no longer be on top.
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.
The youngest layer of sedimentary rock is typically found at the top of a sedimentary rock sequence, as it is the most recently deposited layer. This layer is usually exposed on the Earth's surface, such as in river valleys or coastal areas, where erosion may have removed older layers above it.
The youngest rock is typically found on top in a sequence of rock layers due to the principle of superposition, which states that younger rocks are deposited on top of older rocks. This means that the oldest rock is usually located at the bottom of a sequence of rock layers.
The youngest rock layers are in the center of a syncline fold. This is because syncline folds form when rock layers are bent downward in the middle and upward on the sides, causing the youngest layers to be in the center.
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.

A fold where the youngest rock layers are in the center is called an anticline. In an anticline, the rock layers are folded upwards, creating a convex shape with the oldest layers on the outside and the youngest layers in the center.
