• principle of lateral continuity

• principle of superposition

Which of Steno’s principles is responsible for the folded layers found in the Grand Canyon?

Which principle states that rock layers with the same unique grouping of fossils are of the same geologic age?

• faunal succesion

• fossil horizontality

• fossil superposition

• fossil correlation

Smith and Cuvier discovered that similar groups of fossils in distant rock layers could be correlated. Why was this such a major breakthrough in geology?

• It disproved the principle of superposition.

• It proved igneous rocks held more information than sedimentary rocks.

• Fossils could now be used to identify rock layers.

• Fossils were no longer needed to study the history of Earth.

Which principle states that the processes occurring on Earth today are the same as those that occurred in the past?

• principle of uniformitarianism

• principle of superposition

• principle of fossil correlation

• principle of original horizontality

Why can the geologic record be analyzed by looking at different rock layers?

• All layers have the same age.

• The layers have different ages with the youngest layers on top.

• The layers have different ages with the oldest layers on top.

• The layers have different ages with the youngest layers on bottom.
