How is the principle of superposition used by geologists? 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. … It is one of the great general principles of geology.
How would a geologist use the principle of superposition? Geologists use the law of superposition to determine the relative ages of sedimentary to determine the relative ages of sedimentarty rocks from the sequence of rock layers and the fossils within each layer. … GEologists use radioactive dating to determine the absolute ages of rock.
Why is the principle of superposition important in geology? By applying the law of superposition, we can determine that certain organisms are much older than others, and which geologic times they lived in, because of the fossils preserved in the different layers of sedimentary rocks.
What is the principle of superposition How does it help geologists to determine the ages of rocks? The principle of superposition states that in an undeformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it (Figures 1 and 2). Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.
