The world has thousands of volcanoes, many of them active, and any attempt at a list requires classification. Volcanoes can be grouped according to their type: stratovolcanoes and shield volcanoes, as is done by Oregon State University.Know More
Stratovolcanoes are sometimes known as composite cones, as they are built up by many layers of ash, pumice and other ejecta that has fallen near the base. These volcanoes tend to rise steeply, according to Wikipedia, and are characterized by their sudden, violently explosive eruptions that can sometimes blow the entire summit off the cone. Some active stratovolcanoes are Mt. Fuji in Japan and Tavurvur in Indonesia. Mt. Etna in Italy, is also a stratovolcano, but it is considered dormant.
Shield volcanoes tend to have lower profiles than stratovolcanoes as a result of having been built up almost entirely of liquid lava flows over the years. These flows can continue for a long time and gradually build up a low, massive mountain that resembles a shield resting against the ground. Notable shield volcanoes are Mauna Kea and Mauna Loa, both on the island of Hawaii, and Skjaldbriedour in Iceland. These volcanoes are active, as are 13 of the 21 known shield volcanoes of the Galapagos Island chain.Learn more about Volcanoes

The number of potential active volcanoes on Earth is estimated to be about 1500, with 550 of these having erupted in recorded history. The total number of volcanoes throughout the entire world is unknown, because not all volcanoes are accessible, known and recorded.Full Answer >
Some facts about composite volcanoes include the fact that some of the best-known mountains around the world are composite volcanoes. This list includes Mount Fuji in Japan, Mount Hood in Oregon and Mount St. Helens and Mount Rainier in the state of Washington.Full Answer >
An erupting volcano emits gases and dust particles that can cause profound changes in weather and climate throughout the world. Volcanism also affects the environment by producing acid rain and making ocean water warmer.Full Answer >
