Morphology

volcanism = volcano (transparent) = volcano + ism

The noun denotes the processes related to volcanoes and is directly formed by adding the productive suffix '-ism' to the base concept 'volcano', so the meaning is predictable from the base.

Etymology

Volcanism comes from volcano, which was named after the Roman god Vulcan, 'the god of fire'. So volcanism is the Earth's 'fire' at work, the eruptions of melted rock, gases, and ash that shape the land.
