What does active dormant extinct mean?

Answer 1

Active - a volcano that is still "alive" with the chance of erupting

Dormant - "asleep" or "dead" for many years; hasn't erupted for a while - Opposite of active

Extinct - same thing as dormant, but no chance of erruption

Answer 2

Active means currently in use or functioning, such as an active volcano. Dormant refers to something that is temporarily inactive but has the potential to become active again, like a dormant volcano. Extinct means no longer in existence or functioning, like an extinct volcano that will not erupt again.
