why and how do Volcanoes erupt after being dormant for a long period of time?

Answers

Answer 1

Answer:

Whether a volcano is actually dormant or not, is not actually predictable.

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.

Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another.
