Table Of Contents: Volcano Classification

1. Volcano Classification

Volcanoes are classified by their shape. There are three types of volcanoes—composite, shield and cinder cone.

2. Composite Volcano

A composite volcano forms from alternating layers of ash and layers of flowing lava. Composite volcanoes have steep sides and may have a crater on top.

3. Cinder Cone Volcano

A cinder cone is a small, steep volcano that is created from the accumulation of ash and pyroclastic material. They often have a crater where the top of the volcano was blown off during an explosive eruption.

4. Shield Volcano

Shield volcanoes are wide, flat volcanoes formed by non-explosive lava flows. Layers of hardened lava result in a gently sloping mountain. The Hawaiian Islands were formed from shield volcanoes.
