ANATOMY

Detailed explanation-1: -1. The law of superposition states that each rock layer is older than the one above it. So, the relative age of the rock or fossil in the rock or fossil in the rock is older if it is farther down in the rock layers. Relative dating can be used only when the rock layers have been preserved in their original sequence.

Detailed explanation-2: -The Law of Superposition, which states that older layers will be deeper in a site than more recent layers, was the summary outcome of ‘relative dating’ as observed in geology from the 17th century to the early 20th century.

Detailed explanation-3: -Principle of Original Horizontality As scientists know that the oldest rocks formed will be on the bottom, relative dating can determine the surrounding rock ages. This principle can help determine the correct order of layers from oldest to youngest in the following example.

Detailed explanation-4: -Answer and Explanation: In radiometric dating, the law of superposition is used. The law of superposition was put forward by Nicholas Steno, a Danish Geologist. The law was to help scientists determine the sedimentary rocks’ age.

Detailed explanation-5: -Law of Superposition Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth’s history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface.
