The basement is a term sometimes used, and Cratonis another used in a continental context.The Principle of Superposition has it that in a given formation, the top layers are the youngest, and the deeper layers the oldest.
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.

This geological formation is called a syncline. It is a downward fold in the rock layers where the youngest layers are in the center and the oldest are on the outside.
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
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.
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.
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
The geologic law that scientists use to date the crust by studying the layers of rocks is the Law of Superposition. This law states that in a sequence of undisturbed rock layers, the oldest rock layer will be at the bottom and the youngest will be at the top. By studying the relative positions of these rock layers, scientists can determine the relative ages of the rocks.

The oldest rocks (layers) are at the bottom. The youngestrocks (layers) are at the top
The layers of rock in order from oldest to newest are: Paleozoic, Mesozoic, and Cenozoic. Each of these eras represents a different time period in Earth's history, with the Paleozoic being the oldest and the Cenozoic being the most recent.
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.
The oldest is on bottom and youngest on top.
The furthest down of all top layers.
Scientists study layers of rocks to learn about the earth and how it has changed. They know that if layers are undisturbed, the oldest rocks are on the bottom and the youngest rocks are on top. They know how old each layer is in relation to the other layers.
The simple answer is that the old rock is at the bottom and the young rock is at the top. But sometimes the Earth has folded its skin over so it's all sideways or even upside down. You can see seashells at 5,000 metres up the Himalayas. The newest rocks are those formed where the crust is spreading, or as lava flows from volcanoes. This rock was liquified and mixed in its magma form. The oldest rocks are near the centers of continents, mainly underground but occasionally exposed by upthrust folding and/or erosion.
