What are the types of volcanoes ?

Question

In Earth pls.

Answer 1

Volcanologists have classified volcanoes into groups based on the shape of the volcano, the materials they are built of, and the way the volcano erupts.

The groups are:

* Composite Volcanoes (also called strato volcanoes),
* Shield Volcanoes (also called shields),
* Cinder Cones,
* Spatter Cones, and
* Complex Volcanoes (also called compound volcanoes).

Composite volcanoes, also called strato volcanoes, are formed by alternating layers of lava and rock fragments. This is the reason they are called composite.

Strato-volcanoes often form impressive, snow-capped peaks which are often exceeding 2500m in height, 1000sq.km in surface, and 400km3 in volume.

Between eruptions they are often so quiet they seem extinct. To witness the start of a great eruption requires luck or very careful surveillance.

Composite volcanoes usually erupt in an explosive way. This is usually caused by viscous magma. When very viscous magma rises to the surface, it usually clogs the craterpipe, and gas in the craterpipe gets locked up. Therefore, the pressure will increase resulting in an explosive eruption.

Although strato-volcanoes are usually large and conical, we can distinguish different shapes of them: concave (like Agua), pyramidal (like Stromboli), convex-concave (like Vesuvius), helmet-shaped (like Mount Rainier), collapse caldera (like Graciosa), nested (like El Piton in Teide), multiple summits (like Shasta), elongated along a fissure (like Hekla).

Different Shapes of Composite Volcanoes.

Strato-volcanoes are constructed along subduction zones. Examples of composite volcanoes include Mount Hood, Mount Rainier, Mount Shasta, Mount Fugi, Mount Mayon, and Vesuvius.

Answer 2

There's cinder cones shaped like cones and found in North america, composites also called stratovolcanoes, they are the most common on earth and are usually mountains, shield volcanoes which are made up of entire lava flows and lava domes. Hope this helped:)

Answer 3

Mega is the prefix for a million, so it would be any volcano that has killed a million with the help of the eruption or secondary outcomes alongside with sulphur dioxide reflecting image voltaic lower back into area and cooling the climate. Toba would probable qualify. Thera would additionally be a contender.

Answer 4

Basically there are two kinds.

Ones associated with upwelling of tectonic plates. These erupt but are not explosive.

Ones associated with one tectonic plate subsiding under another. These have explosive erruptions.

Anyway, that's what Ilearnt at uni (30 years ago).
