Which of the following explains how you chose the age of the Coconino sandstone?

• Since the Hermit shale formed 280 million years ago, I picked 275 since Coconino sandstone is above it and newer (fewer years old).

• Since the Hermit shale formed 280 million years ago, I picked 280 since Coconino sandstone is right near it on the diagram.

• Since the Hermit shale formed 280 million years ago, I picked 285 since it is a higher number and the Coconino sandstone is a layer higher.

• Since the Hermit shale formed 280 million years ago, I picked 290 since the Coconino Sandstone looked darker and much older.
