What happens to a volcano once inactive and has no any heat source?
Still releases steam even if there is barely any heat source.
Volcano starts to die out, its cone will erode and weather since no material ejected from beneath.
Its chamber will begin to dig deeper into the mantle until molten materials overflow up to the crater.
The magma chamber breaks down the rocks inside and, with enough heat and pressure, the volcano becomes active again.
