What is the definition of CATASTROPHISM?

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

• A principle that geologic processes that occurred in the past can be explained by current geologic processes.

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

• The principle that states that all geologic change occurs suddenly.

What is the definition of FOSSIL?

• A long cylinder of ice obtained from drilling through ice caps or ice sheets; used to study past climates.

• Faults or intrusions are younger than any layer of rock they cut through.

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

• The weather conditions in an area over a long period of time.

What is the definition of ICE CORE?

• The weather conditions in an area over a long period of time.

• Faults or intrusions are younger than any layer of rock they cut through.

• A long cylinder of ice obtained from drilling through ice caps or ice sheets; used to study past climates.

• An ordered arrangement of rock layers that is based on the relative ages of the rocks (older rocks are at the bottom).

What is the definition of RELATIVE DATING?

• An ordered arrangement of rock layers that is based on the relative ages of the rocks (older rocks are at the bottom).

• Any method of measuring the age of an event or object in years.

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

• A method of determining the absolute age of an object by comparing the amount of parent isotope vs. daughter isotope and using half-life.

What is the definition of ABSOLUTE DATING?

• An ordered arrangement of rock layers that is based on the relative ages of the rocks (older rocks are at the bottom).

• Any method of measuring the age of an event or object in years.

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

• A method of determining the absolute age of an object by comparing the amount of parent isotope vs. daughter isotope and using half-life.

What is the definition of RADIOMETRIC DATING?

• An ordered arrangement of rock layers that is based on the relative ages of the rocks (older rocks are at the bottom).

• Any method of measuring the age of an event or object in years.

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

• A method of determining the absolute age of an object by comparing the amount of parent isotope vs. daughter isotope and using half-life.

What is the definition of LAW OF SUPERPOSITION?

• A method of determining the absolute age of an object by comparing the amount of parent isotope vs. daughter isotope and using half-life.

• 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.

• Younger rocks lie above older rocks, if layers are left undisturbed.

• Faults or intrusions are younger than any layer of rock they cut through.

What is the definition of GEOLOGIC COLUMN?

• An ordered arrangement of rock layers that is based on the relative ages of the rocks (older rocks are at the bottom).

• Any method of measuring the age of an event or object in years.

• 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.

• Stable isotope that forms after the parent isotope decays.

What is the definition of 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.

• The process in which a radioactive isotope tends to break down into a stable isotope of the same element or another element.

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