Applying The Law Of Superposition Dates Can Be Determined?


Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating. Sedimentary rocks form in layers that pile on top of each other. This is called the Law of Superposition, which helps in determining relative ages of rock. … They are useful because they tell the relative ages of the rock layers they are found in. Steno’s laws of stratigraphy describe the patterns in which rock layers are deposited.

… The rock cycle also gives scientists and engineers an idea on where energy sources and building materials such as marble or granite may be located. The principle that the lower the stratum or layer, the older its age; the oldest layers are at the bottom, and the youngest are at the top. The Law of Superposition states that older rocks are located toward the bottom, under the younger rocks. … This law proves that evolution could have occurred since fossils found deep in rock structures are older, from a different time, where some generations of species did not exist.

If the Law of Superposition were compared to making a deli sandwich, the bottom layer of the bread roll would be placed first. As each item is placed one on top of each other to create the deli sandwich, this would represent layers of rock formed over millions of years formed slowly, one on top of each other. It gives logical reasoning for geologists to determine the history of the rock layers they are studying. The Law of Superposition helps scientists in relative dating, especially when they are comparing similar rock layers that are continents apart or when index fossils are present.

To begin, they employ the rule of superposition to establish the relative ages of sedimentary rock strata. According to the rule of superposition, the oldest sedimentary rock layer lies at the bottom of a horizontal sedimentary rock layer. Each layer above it is younger than the layer beneath it. The presence of white or light-colored sand between darker shale fragments indicates that there was more open water than sand when the layer was deposited.
