Final answer:
An active volcano that is currently erupting or has recently erupted is called an active volcano. On the other hand, a volcano that hasn't erupted in a long time is called a dormant volcano, and a volcano that is not expected to erupt again is called an extinct volcano.
Step-by-step explanation:
An active volcano that is currently erupting or has recently erupted is called an active volcano. These volcanoes release lava, ash, and gases during their eruptions. In contrast, a volcano that hasn't erupted in a long time is called a dormant volcano, and a volcano that is not expected to erupt again is called an extinct volcano.
