What principle of relative age dating states that the older rock forms beneath younger rock?

• lateral continuity

• superposition

• inclusions

• cross-cutting relationships

What principle of relative age dating states that if one rock contains pieces of another rock, the rock containing the pieces is younger than the pieces?

• lateral continuity

• superposition

• inclusions

• original horizontality

• cross-cutting relationships

What principle of relative age dating states that sediments are deposited in large, continuous sheets in all lateral directions?

• lateral continuity

• superposition

• inclusions

• original horizontality

• cross-cutting relationships

What principle of relative age dating states that if one geologic feature cuts across another feature, the feature that cuts across is older?

• lateral continuity

• superposition

• inclusions

• original horizontality

• cross-cutting relationships

What principle of relative age dating states that most rock-forming materials are deposited in horizontal layers?

• lateral continuity

• superposition

• inclusions

• original horizontality

• cross-cutting relationships

A layer of rock that is found is dated to the Jurrasic Period. How could the relative age of a rock layer be determined if there are no index fossils. in it?

• You could drill a hole in the rock and see how long it takes ice to freeze in it to determine its age.

• You could find rocks that look the same somewhere else and date them.

• You could relatively date the rock layers above and below it by looking at the index fossils that are in it to narrow down when it was created.

By looking at the fossil chart, which statement best explains how a rock layer could be relatively dated to the

Pennsylvanian Period?

• The rock layer could have Bathyurus extans in the rock layer below.

• The rock layer could contain Dictyoclostus americanus.

• The rock layer could have Hexamoceras hertzeri in the rock layer above.

• The rock layer could contain Nerinea trinodosa.
