Types of Volcanoes Around the World
This is the RFG(B) group.
This website will tell you about different volcanoes around the world.

Shield Volcanoes

You can find shield volcanoes all around the world. One place you can find many shield volcanoes is in Hawaii,U.S. Hawaii has many volcanoes because of hotspots in the ocean. (A hotspot is an area where hot magma, from far below Earth's surface in the mantle, melts through the crust above it, usually forming a volcano.)
Shield volcanoes are named shield volcanoes because they look like a circular shield. What happens to form a shield volcano is thin layers of lava flow on top of previous layers and harden. This kind of lava flow usually builds a wide, slightly sloped mountain.

Lava Plateau

You can find a lava plateau in many locations.For example, Idaho, Washington, and Oregon.A lava Plateau forms when a continuous flows of lava piles up on top of each other, on a level form.First lava flows through many long cracks and travel a long way before cooling and hardening.Then the lava hardens on top of the previous flow.Over millions of years, this continuous process forms a lava plateau.
Calderas

Calderas form when a volcano make such a big eruption it empties the magma chamber or main vent. When this happens the top of the volcano has no support and fall inside of the volcano. If a caldera were to occur, sometimes a lake will form like the picture. This particular caldera, the one in the picture, can be found in Oregon.
Cinder Cone Volcanoes
We got this picture from http://en.wikipedia.org/wiki/Hawaiʻi_Volcanoes_National_Park.
Cinder cone volcanoes are also popular. A cinder cone volcano is a tall, steep, cone-shaped mountain or hill. What happens to form a cinder cone volcano is if the magma inside it is really thick and stiff, it can form (or produce) cinders, ash, and bombs. These materials can eventually build up around the vent of the volcanoes in a steep, cone-shaped pile. (One time, a volcano formed when a volcano built a cinder cone about 400 meters high!)
Composite Volcanoes
