Check understanding
- Define active, dormant, and extinct volcanoes
- Explain that a dormant volcano is not safe just because it has not erupted recently
- Classify a given volcano based on its eruption history
“If you told your child about a volcano that last erupted 500 years ago, could they explain whether it's active, dormant, or extinct, and why a dormant volcano might still be dangerous?”
