What is the definition of LAW OF CROSSCUTTING?

• 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.

• 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.

What is the definition of PARENT 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 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 GEOLOGY?

• 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 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 is the definition of EMPIRICAL EVIDENCE?

• A testable idea or explanation that leads to scientific investigation.

• The observations, measurements, and other types of data that people gather and test to support and evaluate scientific explanations.

• A systemic study of natural events and conditions.

• A descriptive statement or equation that reliably predicts events under certain conditions.

What is the definition of THEORY?

• A descriptive statement or equation that reliably predicts events under certain conditions.

• The application of science and mathematics to solve real-life problems.

• The process of obtaining information by using the senses; the information obtained by using the senses.

• A system of ideas that explains how things happen, supported by a large body of evidence acquired through scientific investigation.
