The mass extinction that ended the non-avian dinosaurs is tied to an impact whose crater sits under which region?

The answer

About 66 million years ago a ~10 km asteroid punched the Yucatán, leaving the ~180 km Chicxulub crater. The blast, firestorms, and years of sunlight-blocking debris collapsed food chains. Birds are the dinosaurs that made it.

Correct answer: The Yucatán Peninsula (Chicxulub)
