How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another

• only absolute dating finds the age in years

• only relative dating finds the age in years

Scientists studying rock layers classify the top layer as the most recent, followed by older layers that are uncovered as they dig deeper. Which law explains this method of relative dating?

• law of geologic continuity

• law of universal position

• law of lateral continuity

• law of superposition

The evidence in these rock layers BEST supports which conclusion?

• The oldest fossils in this section of rock are trilobites.

• Eurypterids are related to modern-day scorpions and crabs.

• Eurypterids were the least common type of organism in this section

• There is some overlap in the presence of brachiopods and ammonites on Earth.

A teacher gave students this diagram of rock layers. The teacher directed the students to determine the relative age of each rock layer based only on the information presented in the diagram.

Which method can BEST be used by the students to determine the relative age of these layers?

• radiometric dating

• rock type evaluation

• the law of superposition

• law of uniformitarianism

A scientist finds the bones of a dinosaur. What could help the scientist determine the approximate age of the dinosaur bones?

• the birds living in the area of the bones

• the weather conditions in the area of the bones

• the kinds of trees living in the area of the bones

• the index fossils in the area of the bones

Two samples of the same index fossil are found in rock layers across the ocean floor from each other. Which could scientists infer about the rock layers containing the fossils?

• The rock layers are about the same relative age

• Both rock layers formed because of volcanic activity.

• The rock layers experienced the same kinds of erosion

• The same climate existed where both rock layers formed.
