→About Volcanoes
Once a volcano is formed it goes through 3 stages of existence :
: 1. Firstly as a volcano is [[Volcanic Eruption|erupting]] or has recently erupted it is known as an [[Active Volcano]].
: 2. Secondly when a volcano is not currently erupting but is due to erupt again within a period of ten thousand years since its last eruption it is known as a [[Dormant Volcano]].
: 3. Finally if a volcano has not erupted in over 10,000 years it is classified as an [[Extinct Volcano]]. This means that it will never erupt again.
