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 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.

Which of the following chemical reactions is responsible for producing energy in the Sun?

• Helium nuclei combining by nuclear fission

• Oxygen molecules causing combustion of solar fuel cells

• Hydrogen nuclei combining to form Helium through nuclear fusion

Energy within the sun is produced through (a)  

• Nuclear fusion

• Nuclear fission

Answer explanation

Energy within the sun is produced through nuclear fusion, where hydrogen nuclei combine to form helium, releasing vast amounts of energy. Nuclear fission, on the other hand, involves splitting heavy nuclei and does not occur in the sun.

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.
