In undeformed strata, the rocks are typically the densest at the bottom of the sequence. This is due to the process of gravitational settling, where denser rocks sink and accumulate at the bottom over time, creating a denser layering pattern in the strata.
The fundamental concept you are referring to is the Law of Superposition. It states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom, while the youngest rocks are found at the top.
This principle is known as the Law of Superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are located at the bottom while the youngest rocks are found at the top. This principle helps geologists determine the relative ages of rock layers and the sequence of events in Earth's history.
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the 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.
The principle you're referring to is known as the Law of Superposition, which states that in an undeformed sequence of sedimentary rocks, each layer (or bed) is younger than the one beneath it and older than the one above it. Therefore, if a sequence is undeformed, the oldest layers will be at the bottom and the youngest at the top. This principle is fundamental in geology for understanding the relative ages of rock layers and the history of the Earth.

older than the one above it
The youngest rock is typically found on top in a sequence of rock layers due to the principle of superposition, which states that younger rocks are deposited on top of older rocks. This means that the oldest rock is usually located at the bottom of a sequence of rock layers.

The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.

The sequence of events in rock layers can be determined through the principle of superposition, which states that in any undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom. Fossils found in the rock layers can also help determine the relative age of the rocks and the sequence of events that occurred. Additionally, geologists use techniques such as radiometric dating to determine the absolute age of rocks within the sequence.
