Professor, M. Moody Types of volcano - composite and shield. Composite volcanoes are steep-sided volcanoes composed of many layers of volcanic rocks, usually made from thick sticky lava, ash and rock debris (broken pieces). Most of the remaining 40 percent occurs under the oceans.

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash. VOLCANOES. There are two main types of volcano - composite and shield. Cinder cones. Composite volcanoes are steep sided volcanoes that reach great heights on the continents. A Composite Volcanic mountain, or volcano, is very tall. Yellowstone Caldera The Yellowstone Caldera is the location of three supervolcano eruptions.. Iceland Volcanoes Find out more about Grimsvotn volcano, Hekla volcano and Katla volcano which are the most dangerous volcanoes on Iceland.. Composite Volcano Composite volcanoes are volcanic mountains that form on the continental side of subduction zones. They are built from particles and blobs of congealed lava ejected from a single vent. A composite volcano is also commonly called a stratovolcano. The " Ring of Fire " in the Pacific Ocean consists of stratovolcanoes. Composite volcanoes are the most common type of volcano on the Earth’s surface.
Known also as strato volcanoes, their shape is a symmetric cone with steep sides that rise as high as 8,000 feet. Yellowstone Caldera The Yellowstone Caldera is the location of three supervolcano eruptions.. Iceland Volcanoes Find out more about Grimsvotn volcano, Hekla volcano and Katla volcano which are the most dangerous volcanoes on Iceland.. Composite Volcano Composite volcanoes are volcanic mountains that form on the continental side of subduction zones. Composite volcanoes consist of alternating layers of ash and lava flows. Tall conical shaped mountains These volcanoes form tall, conical shaped mountains.

Stratovolcanoes form on the continental side of a subduction zone where the melting oceanic crust forms pools of molten rock in a magma chamber. Famous examples of composite volcanoes include Mount Fuji in Japan, Mount Rainier and Mount St. Helens in Washington State, and Mayon Volcano in the Philippines. In order to understand the true nature of a volcano, it is important to know what kind it is. They … The volcanoes expel a variety of stiff pasty lavas that form thick lava flows. A volcano is a mound, hill or mountain constructed by solid fragments, lava flows, and or dome-like extrusions deposited around a vent from which the material is extruded. Cinder cones are the simplest type of volcano. What is a Composite Volcano?
Geologists generally group volcanoes into four main kinds--cinder cones, composite volcanoes, shield volcanoes, and lava domes. Cinder cone volcanoes have a summit with a bowl shape crater. Taller than shield and cinder cone. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas.
