* Shield Volcanoes - are low and flat and have small, flowing eruptions. Some have diameters of 3-4 Miles and are 1,500 to 2,000 feet high.

* Composite Volcanoes - are a mixture between shield volcanoes and cone volcanoes, their eruptions are explosive. Some composite volcanoes attain two to three thousand meters in height above their bases.

* Cone Volcanoes - are the tallest and largest volcanoes, and they have VERY explosive eruptions. They are less than 300m high
