How is relative time recorded?
Where was the oldest layer of rock found? The youngest rock layer?

All things considered, the proof is in the stones! Every one of these stone layers speaks to a timeframe in Earth's history, so the whole succession of layers is another timetable.

The standard of superposition expresses that the most seasoned sedimentary stone units are at the base, and the most youthful are at the top. In view of this, layer C is most seasoned, trailed by B and A. So the full grouping of occasions is as per the following: Layer C shaped.

Figure 11.13 shows the numerous even layers of sedimentary stone that make up the ravine. This pleasantly delineates the standard of unique horizontality. The most youthful stone layers are at the highest point of the ravine, while the most seasoned are at the base, which is portrayed by the law of superposition.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
