The principle of superposition states that in undisturbed rock layers, the youngest layer of rock will be on the bottom, while the oldest layer will be on the top. select the best answer from the choices provided t or f

False because the oldest layers are found on the bottom not the top.

Option (1)

Explanation:

The seafloor spreading refers to the separation or stretching of the seafloor. It leads to the expansion of the ocean basin and it primarily occurs due to the divergent plate motion, where two plates move in the opposite direction.

In a divergent plate motion, the two plates move apart and the new materials are added to the crust along the Mid-Oceanic ridge (MOR), where the hot magma comes out to the seafloor and solidifies, forming basalt.

The rocks that are present along the Mid-Oceanic ridge are the youngest rocks and the age of the rocks gradually decreases as one moves away from this ridge.

Thus, the correct answer is option (1).
