GENERAL GEOLOGY

Detailed explanation-1: -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-2: -The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

Detailed explanation-3: -Geologists use the law of superposition and law of original horizontality to determine the relative ages of sedimentary rock layers. According to the law of superposition, in horizontal sedimentary rock layers the oldest is at the bottom. Each higher layer is younger than the layer below it.

Detailed explanation-4: -The Law of Superposition Newer or younger rock layers are found on top. Older rock layers are found at the bottom. Scientists can read layers of rock knowing that each layer of sediment is deposited on top of older layers.

Detailed explanation-5: -Students can define the Law of Superposition. • The law says that within a sequence of layers of. sedimentary rock, the oldest layer is at the bottom and. each layer above gets progressively younger. 2.
