The matter thrown out of a volcano while it is erupting is called lava, and it consists of melted rock matter. Before erupting, the lava moves underground towards the opening of the volcano. When it is underground like this, it is called magma.
When a volcano erupts, hot matter is ejected through the vent, which is the opening in the Earth's crust through which magma and volcanic gases are expelled.
Ashfall is the common name given to the ash rocks and other debris that is ejected from a volcano during an eruption.
An underwater volcano. The volcano that made Hawaii was a shield volcano.
Rock that is ejected from a volcano and cools is called volcanic rock or lava rock. This type of rock typically has a fine-grained texture due to rapid cooling.
The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.
"Ejected debris" the the solid material shot into the air by an erupting volcano (as opposed to the gasses ejected by the same eruption).
A vent in the Earth's crust from which lava and other materials are ejected is called a volcano.

Ashfall is the common name given to the ash rocks and other debris that is ejected from a volcano during an eruption.
parasitic cone
A cinder cone volcano is built almost entirely from ejected lava fragments. These fragments can range in size from ash to bombs and are ejected during explosive eruptions. Over time, these layers of eruptive material accumulate to form a steep-sided cone-shaped volcano.

Scoria is a frothy form of lava ejected from a volcano as individual pieces.
