The Giant's Causeway is a natural formation dating back to roughly how many million years ago?

The question tests your understanding of how scientists estimate when a rock formation formed using volcanic dating methods. The Giant’s Causeway came from a volcanic eruption that produced lava which cooled and contracted to form the famous hexagonal basalt columns. Geologists date such basalt rocks with radiometric techniques, placing this volcanic activity in the Paleocene, roughly around 60 million years ago. Among the given options, fifty million years ago is the closest fit to that widely cited age, which is why it’s considered the best choice. The other ages are notably younger than the well-established timeframe for this formation.
