While studying a section of the Grand Canyon, a geologist tries to determine the age of rock layers. Which statement correctly compares techniques used in this scenario?

• Core rock samples from the canyon indicate absolute age, but radioactive dating of these samples indicates relative age.

• Radioactive dating of rocks from the canyon indicates absolute age, but the law of superposition applied to these layers indicates relative age.
