composite volcanoes
A cone shaped mountain that is built from layers of lava is called a volcano.However, that description does not quite fit any of the three accepted descriptions of the world's volcanoes.A dome shaped mountain built from layers of lavais called a 'shield volcano'.A cone shaped mountain built from layers of cinders (tephra) is called a 'cinder cone' or a 'cinder cone volcano'.A cone shaped mountain built from alternating layers of lava and cinders is called a 'composite volcano'.
Tephra
The smallest size of volcanic tephra is Ash, particles smaller than 2 mm (0.08 inches) in diameter.
Cinder Cone
A combination volcano develops from repeated lava eruptions and the accompanying tephra deposits Tephra is the debris from the eruption..
when volcanic ash bursts out of the volcano, its called an eruption.^^^Actually, when ash and cinders are blown violently out of volcanoes, it's called a tephra. :3
Composite
composite
Tephra is basically ash, rock, cinders, and solidified lava spurted from a volcano.
Volcanic ash, cinders, and bombs are called tephra.

Tephra is produced naturally by volcanic eruptions and refers to the material produced when the volcano erupts. Tephra comes in a range of forms and are classified by size Ash, Lapilli or Volcanic blocks.
Tephra, the material ejected into the air during an explosive volcanic eruption, consists of molten lava materials such as pumice, cinders, and volcanic ash that have cooled and solidified as they fell through the air. Large tephra deposits form where the material lands and eventually become compacted into rock called volcanic tuff.
