What happens when a volcano goes to sleep?

When a volcano goes to sleep, it becomes dormant, meaning there is no volcanic activity or eruption occurring. However, this does not mean the volcano is extinct, as it can wake up and become active again in the future. During this dormant period, magma may still be present beneath the surface, but there is no immediate threat of eruption.

How many years does it take to form volcanoes?

Because of an erruption a volcano often collapses or shrinks, so then it takes many years again. A new volcano can also be formed in the crater of an old volcano.
