In disturbed sediments without layers, the relative age of the sediments would be unknown.
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
No, the Law of Thermodynamics does not pertain to the arrangement of sediment layers. The principle you are referring to is known as the Law of Superposition in geology, which states that in undisturbed layers of rock, the oldest layers are found at the bottom and the youngest at the top.
Sedimentation of transported weathered and eroded material is continuous, cyclical, or event based. New sediments are deposited on top of existing sediments, forming layers that may be visible in a sedimentary rock body.

Undistributed rock layers may indicate that the layers have not been disturbed or deformed from their original horizontal positions. The oldest rock layers are typically found at the bottom of a sequence, while the youngest rock layers are found at the top, following the principle of superposition in geology.
Deep in the ground.
The furthest down of all top layers.
The oldest organisms can generally be found in the lower layers of rock, as these layers were formed earlier than the upper layers. By examining the relative positions of different rock layers, scientists can determine the ages of the organisms found within them.
