Question

A clast of granite found in a conglomerate is determined to be 100 million years old. What does this information suggest about the conglomerate?

Answer 1

The age of the clast of granite suggests that the conglomerate is at least 100 million years old.

Step-by-step explanation:

The age of the clast of granite found in the conglomerate, which is determined to be 100 million years old, suggests that the conglomerate itself is at least as old as that. This is because the clast of granite must have formed before it was incorporated into the conglomerate. Therefore, the information suggests that the conglomerate is at least 100 million years old.
