Final answer:
The Mono Craters are a chain of young calderas, which are large volcanic craters that form when a volcano collapses upon itself after a massive eruption.
Step-by-step explanation:
The Mono Craters are a chain of young calderas, which are large volcanic craters that form when a volcano collapses upon itself after a massive eruption.
