Volcano output is composed of four main components: ASH (3 letters), ejecta (6 letters), MAGMA (5 letters), and LAVA (4 letters). ASH is the fine particles of rock and glass that are ejected from a volcano during an eruption. Ejecta is the material that is thrown out of a volcano during an eruption. MAGMA is molten rock that is located beneath the surface of the Earth. LAVA is molten rock that is expelled from a volcano during an eruption. Molten LAVA is the term used to describe the liquid form of LAVA.
