Question: Which is older A or B What principle?

Which layer is older A or B?

The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers. 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.

Which of the following layers is the oldest?

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.

What is Charles Lyell theory?

Lyell argued that the formation of Earths crust took place through countless small changes occurring over vast periods of time, all according to known natural laws. His uniformitarian proposal was that the forces molding the planet today have operated continuously throughout its history.

What are 3 examples of uniformitarianism?

Modern View of Uniformitarianism Good examples are the reshaping of a coastline by a tsunami, deposition of mud by a flooding river, the devastation wrought by a volcanic explosion, or a mass extinction caused by an asteroid impact. The modern view of uniformitarianism incorporates both rates of geologic processes.
