Question

what makes a volcano dead?​

Answer 1

Answer:

An extinct volcano is “dead” — it hasn't erupted in the past 10,000 years and is not expected to ever erupt again. ... For example, if a volcano's eruptive history shows that it usually erupts every 10,000 years or so, and there hasn't been an eruption for a million years, it may be called extinct.

Answer 2

Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.[1] Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates.
