Geology Quiz: Part 14

What is the Law of Superposition in geology?

• The layers are randomly arranged

• The oldest layer is on top and the youngest on bottom

• The youngest layer is on top and the oldest on bottom

• The layers are arranged based on their color

What is the Principle of Faunal Succession?

• It states that sedimentary strata contain only plant fossils

• It states that sedimentary strata contain fossils in a random sequence

• It states that sedimentary strata contain fossils in a definite sequence

• It states that sedimentary strata do not contain any fossils

What is the Principle of Lateral Continuity?

• Strata originally extended in all directions until they terminated against the edges of their original depositional basin

• Strata were originally deposited horizontally under gravity action

• The geologic feature which cuts another is the younger of the two

• Each layer of an undeformed sedimentary sequence is younger than the one beneath it and older than the one above it

What is the main focus of the new science of Paleontology?

• The study of ancient geological formations

• The study of ancient plant species

• The study of ancient civilizations

• The study of ancient life-forms

What are Foraminifera?

• Marine zooplankton and benthos with calcite shells

• Marine shellfish

• Terrestrial plant species

• Extinct reptiles called dinosaurs

What is the main problem with the stratigraphic laws according to the text?

• Geologists always found gaps in a succession

• None of the above

• It is difficult to determine the relative ages of formations that are widely separated in space

• Both A and B

What is the Law of Original Horizontality in geology?

• Strata originally extended in all directions until they terminated against the edges of their original depositional basin

• Sedimentary layers were originally deposited horizontally under gravity action

• The youngest layer is on top and the oldest on bottom

• The geologic feature which cuts another is the younger of the two

What are Ammonites according to the text?

• Marine shellfish

• Extinct reptiles called dinosaurs

• Marine zooplankton and benthos with calcite shells

• Terrestrial plant species
