The inner core of a volcano is solid primarily due to the immense pressure exerted by the overlying layers of rock and magma. This high pressure raises the melting point of the materials present, preventing them from becoming molten despite the high temperatures. Additionally, the composition of the inner core, which includes dense minerals, contributes to its solid state. As a result, the inner core remains solid while surrounding areas may be liquid or semi-liquid.
