Very hot gases, ash and volcanic bombs are categorized as what?

Explanation:
Explosive volcanic activity produces materials that are ejected as a hot mixture of fragments and gases. The term that covers this eruptive debris, including ash and volcanic bombs, is pyroclastic material. It specifically refers to the materials expelled during an eruption, often accompanied by hot gases, rather than molten rock that flows on the surface (lava flow) or rock that remains beneath the surface (magma). Tephra is a broader label for all fragmented ejecta, but the inclusion of hot gases and the way these ejecta are produced are best described by pyroclastic material.
