The absolute age of an igneous rock can best be determined by ___________.

• examining the environment in which the rock is found

• examining the rock’s relative position in a rock outcrop

• comparing the amount of decayed and undecayed radioactive isotopes

• comparing the size of crystals in the upper and lower parts of the rock

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

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

• 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 involves testing of sedimentary rocks while a relative date involves testing of igneous rocks.

Where do the oldest rocks found in an undisturbed rock profile?

• at the bottom

• in the middle

• on the top

• anywhere
