what is the difference between a active, dormant extinct volcano

A active volcano is a volcano that has erupted in 10,000 years ago which is a very very very long time. A dormant Volcano is a Volcano that is sleeping but they will wake up because they are going to erupt. The dormant volcano will consistently erupt until there is no more lava in a dormant Volcano. A extinct volcano is a Volcano that won’t erupt because it has no more lava in a volcano like Mt Wellington that is a extinct volcano so it is safe to climb it and also to walk around it therefore it won’t erupt again.
