Scientists use the principle of superposition to date rocks based on their layers in the Earth's strata. This principle states that in undisturbed sedimentary rock layers, the oldest rocks are typically found at the bottom, while the younger rocks are located at the top. Therefore, a rock that is deeper down in a geological formation is generally considered to be older than a rock that is closer to the surface. Additionally, scientists can use radiometric dating techniques to determine the absolute age of the rocks, further refining their understanding of the geological timeline.
In 3-5 sentences explain your response.
How can scientists date rocks based on the order they are discovered? In other words, how does a rocker deeper down compare to one on the surface in age?
