Shield Volcano:  A broad domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.

Answer 2

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 <span />
