Shield Volcano
Composite Volcano
Cinder Cones
Lava Domes
__________is a wide volcano with shallowly-sloping sides. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano
Shield Volcano
Composite Volcano
Cone Volcano
Lava Dome
______are mounds of viscous lava and rocks that pile up and accumulate around a volcanic vent. Lava dome is created when the escaping lava collects around the edges of the opening. Because the lava is often extremely thick, it can't flow very quickly. So instead of running off the sides of the vent, it collects around the opening. It creates a Dome.

Composite Volcano
Cinder Cone
Lava Dome
