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.

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.

What is the definition of EXPERIMENT?

• The giving up of one thing in return for another, often applied to the engineering design process.

• An organized procedure to study something under controlled conditions.

• Information gathered by observation or experimentation that can be used in calculating or reasoning.

• The application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs.

What is the definition of OBSERVATION?

• A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept.

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

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

• The application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs.

What is the definition of MATERIALS SCIENCE?

• The study of the characteristics and uses of materials in science and technology.

• A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept.

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

• In a scientific investigation, the factor that is deliberately manipulated.
