What part of the Earth’s internal core is important in forming volcanoes?

inner core

Explanation:

Growth is less concentrated around “superplumes” or LLSVPs. These ballooning masses of superheated mantle rock likely influence “hot spot” volcanism in the lithosphere, and contribute to a more liquid outer core.

Earth's core is the very hot, very dense center of our planet. ... from planetary formation, and heat released as the liquid outer core ... Temperature in the inner core is about 5,200° Celsius (9,392° ... the core and cool the surrounding area, causing increased instances of ... Some hot spots produce volcanoes.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
