Absolute and Relative Dating

Multiple Choice

Which type of dating method can be used on rock layers by applying the Law of Superposition?

Multiple Choice

What is the difference between an absolute date and a relative date?

• A relative date is derived from radiometric dating techniques while an absolute date comes from guesswork.

• A relative date refers to a year or a range of years while an absolute date indicates a chronological order.

• An absolute date refers to a year or a range of years while a relative date indicates a chronological order.

• An absolute date involves testing of sedimentary rocks while relative date involves testing of igneous rocks.
