According to the law of superposition, which layer is the
oldest?
1
2
3
4

4

Explanation: The law of superposition states that in a sequence of rock layers, the youngest layer is on the top, and the oldest one is on the bottom, each being younger than the one beneath it and older than the one above it.

Option (4)

Explanation:

The law of Superposition was introduced by Nicolas Steno. According to this law, in an undisturbed sedimentary rock sequence, the rock layer that is present at the base of the sequence depicts the oldest rocks as these rocks were the first to deposit on this area. And the rock layer that is present at the extreme apical portion of the entire sequence is considered to be youngest rocks, as they have been deposited very recently.

This law is very simple and is an easy identification of the oldest and youngest rocks in a sedimentary rock sequence.

Thus, in the given image, the oldest rock layer is layer 4 and the youngest rock layer is layer 1.

Hence, the correct answer is option (4).
