ROCK LAYERS

Which field of science deals with the study of rock layers?

• Geology

• Petrology

• Paleontology

• Stratigraphy

Which processes most often cause fossil evidence to be preserved in rock?

• melting and faulting

• weathering and erosion

• folding and metamorphism

• cementation and deposition

Which of the following laws of stratigraphy gives emphasis on the assemblage of fossils embedded on rock layers?

• Law of Conformities

• Law of Superposition

• Law of Faunal Succession

• Law of Original horizontality

What can be concluded if a dike protrudes through several layers of rock?

• A batholith resides nearby.

• A volcano is within the area.

• It is formed before the rock layer.

• The rock layers are formed before the dike protrudes.

Who proposed the Law of Uniformitarianism?

• Aristotle

• Nicolas Steno

• James Hutton

• James Chadwick

Which principle states that the physical, chemical, and biological processes that work today are the same forces that worked in the past?

• Principle of Intrusions

• Principle of Unconformities

• Principle of Uniformitarianism

• Principle of Original Horizontality

According to the Law of Superposition, where are the oldest fossils usually found?

• somewhat near the surface

• at the top of the rock layers

• in the middle of the rock layers

• near the bottom of the rock layers

How is the principle of original horizontality described?

• All rocks were originally horizontal.

• Each layer of rock is older than the one above it.

• The original crust of the earth was almost perfectly flat

• Layers of sediments are deposited in a nearly horizontal orientation.
