Knowing the age of rocks important for understanding the history of Earth.  One method for doing this is radioactive dating.  This method allows geologists to _.

• tell the difference between molds and casts.

• tell where one soil horizon ends and the next one begins.

• determine the absolute ages of rocks.

• determine the relative ages of rock layers.
