The oldest layers of undisturbed sediment are at the bottom.
In disturbed sediments without layers, the relative age of the sediments would be unknown.
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.
Under normal conditions, the largest, or the sediments with the most mass, are the first to be laid down, as they are able to more easily resist the force causing the movement of the sediments. Successively smaller particles are laid down after that, as deposition continues.
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.
The law that states the oldest layers of sediment will be located on the bottom is called the Law of Superposition. This principle is fundamental in understanding the relative ages of rock layers in geology.

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.
Layers represent different periods of time. They are caused by factors such as wind, water, and gravity hardening them into distinct layer.
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.

The oldest sediments are generally younger than the oldest continental rocks. Sediments are continuously being deposited on the Earth's surface, while continental rocks have undergone processes of solidification and deformation over billions of years. This means that the oldest continental rocks are usually much older than the oldest sediments.
