What is the definition of DAUGHTER ISOTOPE?

• Isotope that is unstable and decays; also called a radioactive isotope.

• Stable isotope that forms after the parent isotope decays.

• The time required for half of a sample of a radioactive isotope to break down by radioactive decay to form a daughter isotope.

• Any method of determining whether an event or object is older or younger than other events or objects.

What is the definition of INDEX FOSSIL?

• Any method of determining whether an event or object is older or younger than other events or objects.

• The standard method used to divide Earth's long natural history into manageable intervals of time.

• Fossils that are used to estimate the absolute age of the rock layers in which they are found. These organisms must have lived during a short time span, have unique features, and be common over large areas.

• The trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock.

What is the definition of GEOLOGIC TIME SCALE?

• The trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock.

• The standard method used to divide Earth's long natural history into manageable intervals of time.

• All fossils discovered on Earth.

• The scientific study of the origin, history, and structure of Earth and the processes that shape Earth.

What are the limits on the things that scientists can study in their work?

• They can study only phenomena that they can observe or model.

• They can study only events that take place on Earth.

• They can investigate only questions that they were the first to ask,

• They can investigate only the areas of science in which they are experts.

Imagine that the label on a sunscreen product reads, " Recommended by 9 out of 10 doctors." No other information regarding this claim is provided. Why would a scientist tell a consumer to be wary of this statistical claim?

• Sunscreen products do not work.

• The supporting scientific data is missing.

• The claim is impossible to confirm or dispute.

• The claim cannot be reevaluated when new information emerges.
