Answer 2

A volcano that is erupting or has erupted in the last 100 years is called an active volcano. According to scientists, a volcano that has a history of having erupted within the last 10,000 years is still likely to erupt again in the future therefore it is considered active. If a volcano has not erupted within the last 10,000 years, then it is classified as dormant. If there is no known history of the volcano erupting then it is classified as extinct. It is however important to note that it is sometimes there are very minimal diffrences between dormant and active volcanoes.
