The part of the conduit that ejects lava and volcanic ash. Ash-Fragments of lava or rock smaller than 2 mm in size that are blasted into the air by volcanic explosions.

There are different types of volcanoes based on their size, shape, composition and eruptive style.Composite cone volcanoes are cone-shaped volcanoes composed of layers of lava, ash and rock debris.olcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected.
