Each sedimentary layer of rock represents 1, 000 years of Earth’s age, much like the rings of a tree.
|
|
|
In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers.
|
|
|
In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
|
|
|
Rocks that form near volcanoes are older than surrounding rock.

Detailed explanation-1: -law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
Detailed explanation-2: -The most basic law listed here is the law of superposition, which says rock layers at the top are younger than rock layers at the bottom.
Detailed explanation-3: -The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed. Layer B formed.
Detailed explanation-4: -Relative chronology is based on a classic geological principle, known as the Law of Superposition. This law holds that, under normal circumstances, deeper layers of soil, sediment, or rock are older than those above them.
Detailed explanation-5: -The law of superposition is one of the principles of geology scientists use to determine the relative ages of rock strata, or layers. This principle states that layers of rock are superimposed, or laid down one on top of another. The oldest rock strata will be on the bottom and the youngest at the top.
