Question

Which of the following is the strongest criterion for superposition?

1.Cross bedding

2.Graded bedding

3.Convolute bedding

4.Index fossil

​

Answer 1

The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy. It is a form of relative dating. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. This is important to stratigraphic dating, which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed. In the simplest way to explain it that is possible, sedimentary rock that has not been moved around will have the oldest layers on the bottom, meaning that any fossils found inside will be older or newer depending where they are in the rock.
