1. Stratovolcanoes: These are steep-sided, usually conical volcanoes consisting of layers of ash plus rock fragments and lava flows.
2. Shield volcanoes: These are broad, gently inclined volcanoes composed of alternating layers of solidified lava and ash.
3. Cinder cones: These are the simplest type of volcano, consisting of loose pyroclastic material around a volcanic vent.
4. Lava domes: These are dome shaped features built of viscous, "sticky" lava.
5. Calderas: These are large circular or oval depressions resulting from the collapse of a volcanic cone.
