Science State Test Review

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 RADIOACTIVE DECAY?

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

• 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 HALF-LIFE?

• 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 UNIFORMITARIANISM?

• 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.

Which of the following best defines science?

• A collection of unchangeable facts about the natural world

• The study of the natural world through observation, identification, description, experimental investigation, and theoretical explanations

• A belief system based on assumptions about the natural world

• A method for proving theories beyond doubt

DOK Level 1: Recall

What is the role of evidence in modifying scientific theories?

• Evidence is rarely considered when modifying theories.

• Evidence can refute or support theories, leading to modifications.

• Theories are modified first, then evidence is found to support the changes.

• Evidence is only used to confirm existing theories, not modify them.

DOK Level 3: Strategic Thinking

What is a common method for scientists to communicate their research findings?

• Through artistic performances

• By publishing in scientific journals

• By creating infomercials

• Through political debates

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 FOSSIL RECORD?

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

• All fossils discovered on Earth.

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

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