Types of Volcanoes

The cinder cone is the simplest type of volcano. It forms a steep, cone-shaped hill made up of loose volcanic fragments called pyroclastic materials. These volcanoes may be small, but they have distinctive steep sides.

A lava dome is a circular, mound-shaped formation created when thick, sticky lava slowly pushes up from a volcano but doesn't flow very far. The viscous (thick) lava piles up around the vent, creating a dome-like structure.

Composite volcanoes are the most explosive and destructive volcanoes in the world. They're built from alternating layers of ash and lava that build up over time. These volcanoes can create massive eruptions that affect large areas.

Shield volcanoes are mainly made of basaltic or andesitic lava flows. Unlike steep volcanoes, shield volcanoes have a low, wide profile because their runny lava flows far from the source, creating a shape that resembles a warrior's shield.

Fun Fact: Hawaii's famous volcanoes are mostly shield volcanoes, while Mount St. Helens is an example of a composite volcano that showed just how destructive this type can be!
