Quizplus · Accepted Answer

The type of material present in the landslide at the bottom of the right column would be least useful in correlating the ages of these two sequences of rocks because it is not directly related to the age of the rocks. The other options (numeric ages on volcanic rocks, pattern of magnetic reversals, and overall sequence) would provide more direct information about the ages of the rocks.
