The types of Volcanoes

There are 4 types of volcanoes and these are Cinder cones, Composite volcanoes, Shield volcanoes and lavas domes.

Cinder cones volcanoes are the simplest type of volcanoes they are built from blobs of congelated lava ejected from a single vent. As the gas lava is blown violently into the air, it breks down into smaller particles that solidify and fall as cinders, around a vent to form a circular or oval cone. Almost all of the cinder cone volcanoes have a bowl shaped crater. They are numerous at the western norh America.

Composite volcanoes are some of the world greatestt mountains, and they are sometimes called Stratovolcanoes. They are steep sided, symmetrical cones of large dimmention built of alternating layers of lava flows, vocanic ash, cinders, blocks and bombs. One of the most known of omposite volcanoes is the Mount Fuji in Japan.

Shield Volcanoes are almost built entirely of lava flows. This types of volcanoes are the ones most big of the world. It has a sloping cone flat, domical shape.



Lava Domes are formed by small viscous lava flows that cannot flow any great distance. A dome grows larger by expasion from within. When it grows its outer surface cools and hardens and then shatters. Volcanic domes communly occur within the craters or on the flanks of arge composite volcanoes
