Types of Volcanoes This is the famous 3 types of volcanoes (shield volcanoes, strato volcanoes, and cinder cones), and it is found in many textbooks from elementary school to college.ertainly there are different ways to classify volcanoes and all of them have particular benefits and drawbacks. These include classifying by lava chemistry, tectonic setting, size, eruptive character, geographic location, present activity, and morphology.

Types of volcanic eruptions There are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions. Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra. Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption.lows from Hawaiian eruptions are basaltic, and can be divided into two types by their structural characteristics. Pahoehoe lava is a relatively smooth lava flow that can be billowy or ropey. They can move as one sheet, by the advancement of toes, or as a snaking lava column.

- There are all kinds of volcanoes on Earth—active, dormant, and extinct volcanoes, volcanoes that explode with ash and gas, and volcanoes that have slow rivers of melted rock (known as lava). Volcanoes on Earth have been responsible for the destruction of cities, the extinction of species, and changes in Earth’s climate.

Volcano Types Volcanoes are distinguished by their eruption style, composition, and structure. Volcanoes act differently and form differently because they are made up of different types of rocks and minerals. Below is a description of common volcano types that can be recognized as distinguishable land formations. For more than 200 years keen observers have noted that some volcanic eruptions affect weather and climate. Scientists report that large eruptions at low latitudes can cause the greatest global climate change.

Volcanic eruptions and environment There are different types of volcanic eruptions: - Phreatic: explosion of steam, water, ash and rock as magma comes in contact with groundwater or surface water. - Rhyolite flow: high-silica lava (>68%) - Basalt flow: low-silica lava (when the silica content is low, lava usually has a higher magnesium and iron content)

Shield volcanoes are the largest volcanoes on Earth.The basaltic lava can pile up producing huge shields with gentle slopes and convex outlines.hield volcanoes have very fluid lava composed almost entirely of basalt.

Types of volcanic eruptions Several types of volcanic eruptions —during which lava, tephra (ash, lapilli, volcanic bombs and blocks), and assorted gases are expelled from a volcanic vent or fissure —have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. The strongest types of eruptions, with a VEI of 8, are so-called Ultra-Plinian eruptions, such as the most recent one at Lake Toba 74 thousand years ago, which put out 2800 times the material erupted by Mount St. Helens in 1980.

Types of volcano Types of volcano. When magma erupts at the surface it can form different types of volcanoes depending on the viscosity, or stickiness, of the magma, the amount of gas in the magma, and the way in which the magma reached the surface.agma is stored beneath a volcano in a magma chamber. When a very large explosive eruption occurs which empties the magma chamber, the roof of the magma chamber can collapse forming a depression, or bowl on the surface which has very steep walls.

Principal Types of Volcanoes S ome of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases. inder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

- The three types of volcanoes are shield, cinder cone and composite volcano. Volcanoes are created when heated, melted rock, magma rises to the surface of the Earth. The three types of volcanoes differ in the type of material that actually reaches the surface and the type of eruption that occurs. Full Answer >.

Volcano Types Often cinder cones are classed as a major type of volcano. But cinder cones are much smaller than most shield, composite, and ash flow volcanoes. In fact, cinder cones occur on all of these larger volcano types.Image at left: A schematic representation of the internal structure of a typical cinder cone.here are two stratovolcanoes, one shield volcano, and one volcano that appears to be formed from overlapping stratovolcanoes.

Stratovolcanoes, or composite volcanoes, get their name from the different layers, or strata, of ash and lava that form them.Most stratovolcanoes are irregularly shaped mountains formed by material ejected from both a central vent and other vents on the sides of the mountain.cientists recognize four main types of volcanoes: stratovolcanoes, shield volcanoes, cinder cones, and ashflow calderas.

Types of Volcanic Eruptions Volcanologists classify eruptions into several different types. Some are named for particular volcanoes where the type of eruption is common; others concern the resulting shape of the eruptive products or the place where the eruptions occur.Here are some of the most common types of eruptions:In a Hawaiian eruption, fluid basaltic lava is thrown into the air in jets from a vent or line of vents (a fissure) at the summit or on the flank of a volcano.ere are some of the most common types of eruptions: In a Hawaiian eruption, fluid basaltic lava is thrown into the air in jets from a vent or line of vents (a fissure) at the summit or on the flank of a volcano.

Composite Volcano [/caption] Geologists have identified 3 major types of volcanoes. There’s the shield volcano, formed from low viscosity lava that can flow long distances. There are cinder cone volcanoes, which are made by the eruption of lava, ash and rocks that build up around a volcanic vent. But the last type is the composite volcano, and […]

- Volcanoes come in all shapes and sizes. The more common types are shield volcanoes, stratovolcanoes, and cinder cones. Shield volcanoes gained their name from the fact that their profile against the horizon looks like a shield laying on the ground. The flanks of a shield volcano have low slopes, sometimes only a few degrees from horizontal. Shield volcanoes are the largest volcanic features on earth. The largest shield volcano, Mauna Loa in the Hawaiian Islands, has a volume 300 times greater than that of the largest stratovolcano, Mount Fuji in Japan.

Types of Volcanic Eruptions The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.olcanologists classify eruptions into several different types. Some are named for particular volcanoes where the type of eruption is common; others concern the resulting shape of the eruptive products or the place where the eruptions occur. Here are some of the most common types of eruptions:

Types of Volcanoes: Shield, Cinder Cones & Composite Cones Volcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. There are different types of volcanoes based on their size, shape, composition and eruptive style. Composite cone volcanoes are cone-shaped volcanoes composed of layers of lava, ash and rock debris. Composite cone volcanoes can grow to heights of 8,000 feet or more and have explosive eruptions. Shield volcanoes are broad, domed-shaped volcanoes with long, gently sloped sides.

Volcano Strato/composite volcanoes are made of cinders, ash, and lava. Cinders and ash pile on top of each other, lava flows on top of the ash, where it cools and hardens, and then the process repeats. Classic examples include Mt. Fuji in Japan, Mayon Volcano in the Philippines, and Mount Vesuvius and Stromboli in Italy.
