Question: Is layer a older or younger than layer C?

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.

Is Layer B older or younger than layer C?

By the law of superposition, C is the oldest sedimentary rock, B is younger and A is still younger. The full sequence of events is: Layer C formed. Layer B formed.

How do you know if a layer is older or younger?

Superposition. Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.

Is the top layer the oldest?

The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.

Is fault H older or younger than rock layers a D?
