• Composite Volcano

• Lava domes

_____________ also called as STRATOVOLCANOES. It can rise-up to TEN THOUSAND feet above their base. It also has a Secondary Vent

• 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.
