The three types of volcanoes are called shield, cinder cones and composite cones.
Shield: it is a type of volcano usually built almost entirely of fluid lava flows.
Cinder Cones: it is a steep conical hill of loose pyroclastic fragments, such as either volcanic clickers, cinder, volcanic ash or scoria that has been built around a volcanic vent.
Composite: it is built up with many layers of hardened lava and volcanic ash
