According to the principle of faunal succession, what must be true of the fossils on a layer below?

• younger than the fossils above

• older than the fossils in the layer above

• the same age as the fossils in the layers above

• identical to the fossils in the layers above

Answer explanation

What does the principle of faunal succession state?

• Absolute dating is required to determine the relative age of animals based on their fossils.

• Specific groups of organisms have followed one another in a definite sequence through the Earth's history.

• Rock layers with the same unique grouping of fossils are of the same geologic age.

• Fossils are deposited in approximately horizontal layers and spread out until they reach a barrier.

What does the principle of uniformitarianism state?

• Younger rocks are deposited on top of older rocks in undisturbed sedimentary rock layers.

• Specific groups of organisms have followed, or succeeded, one another in a definite sequence through Earth's history.

• Sedimentary rocks are deposited in approximately horizontal layers; if they are not horizontal, they have been rearranged by the action of forces within the Earth.

• Geologic processes taking place on the Earth today operated similarly in the past and can be used to explain past geologic events.

Which statement best describes the geological processes throughout history?

• Geologic processes that shape the Earth are cyclical.

• Geologic processes are only similar in if they occur in the same area.

• Once a geologic process has shaped the Earth, it cannot be repeated.

• Geologic processes are similar if occurring in the same time.
