The one closest to the surface because rock layers are laid down one on top of another.
yes
Superposition is the theory that the rock layer that is on top is the youngest and the layer of rock on the bottom is the oldest.
On the top
The top layer that people walk on is called the earths crust.
According to the Law of Superposition, in a depositional sequence of undisturbed rock layers, the top layer of rock is the most recent to form from the processes of lithification or eruption of lava onto the surface, and are therefore the youngest rock layers.
The top layer. The top layer of any sedimentary rock is most likely the newest in geologic time.

Humus on the top layer
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 bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
The bottom layer of rock in a geologic sequence is usually called the basement layer.
