Detailed explanation-1: -The principle of superposition states that in an undeformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it (Figures 1 and 2). Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.

Detailed explanation-2: -This is called the Law of Superposition in geology. Students in the above images, you see that older layers are on the bottom and therefore the animal fossils found in those older layers are therefore older animals. More recent organisms are found on the top layers.

Detailed explanation-3: -law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

Detailed explanation-4: -The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.

Detailed explanation-5: -The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top.
