FAQ: Which Features Would You Look For To Classify A Volcano?

There is no easy answer to this question, as scientists classify volcanoes in several different ways, including size, shape, explosivity, lava type, and tectonic occurrence. A volcano that has very effusive eruptions, for example, is unlikely to form a stratovolcano.

What are the main features of a volcano?

Volcanoes have distinctive features:

  • magma chamber – this is where the molten rock is stored beneath the ground.
  • main vent – this is the channel through which magma travels to reach the Earth’s surface.
  • secondary vent – some magma may escape through the side of the volcano, particularly if the main vent becomes blocked.

What are the three ways a volcano can be classified?

Scientists have categorized volcanoes into three main categories: active, dormant, and extinct. An active volcano is one which has recently erupted and there is a possibility that it may erupt soon. A dormant volcano is one which has not erupted in a long time but there is a possibility it can erupt in the future.

What are the 2 classification of volcano?

There are two types of classification of volcanoes based on eruption and these are central or explosive and fissure or quiet. An explosive eruption happens because of a buildup of gas under very viscous slow flowing and thick magma.

How many classifications of volcanoes are there?

There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.

What are the 5 structural features of volcano?

Volcanic Features and Landforms

  • Craters. Craters form as the result of explosive eruptive activity at a volcanic vent where rock, magma, and other material is ejected leaving a conical void.
  • Calderas.
  • Diatremes and Maars.
  • Lava Flows.
  • Lava Tubes.
  • Fumaroles.
  • Geothermal Features.

What are structural features of volcano?

Volcanoes typically have a bowl-shaped basin at the top of the volcano, known as a crater. When magma reaches the surface, it is known as lava. Eruptions from other vents may lead to the formation of secondary cones on the flank (side) of the volcano.

How are volcanoes classified based on its periodicity of their eruption?

Answer: On the basis of periodicity of eruption, volcanoes are classified into three types: (i) active volcanoes, (ii) dormant volcanoes, and (iii) extinct volcanoes.

How are volcanoes classified on the basis of the frequency of eruption?

On the basis of frequency of eruption means the number of time volcanoes are erupted. Extinct-Volcanoes which are no longer in the condition of erruption. Active-The constantly errupting volcanoes. Dormant-Volcanoes which have become inactive from a long time but have a possibility of erruption.

Why is volcanic activity classification necessary?

As populations increase, areas near volcanoes are being developed and aviation routes are increasing. As a result, more people and property are at risk from volcanic activity. Comprehensive monitoring provides timely warnings of volcano reawakening. USGS National Volcanic Threat Assessment.

How many groups are volcanoes classified on the basis of nature of eruption and the form developed at the surface explain?

Answer: Two basic classifications of volcanoes are based upon the type of eruption they produce: explosive (or central) and quiet (or fissure). Explosive eruptions are caused by the buildup of gasses under highly viscous (thick and slow-flowing) magma trapped deep within the volcano.

What is the basic of classifying volcano as active or inactive?

Put simply, the most popular way for classifying volcanoes comes down to the frequency of their eruption. Those that erupt regularly are called active, while those that have erupted in historical times but are now quiet are called dormant (or inactive).

What do you understand by a volcano explain about the types of volcanoes?

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes. Composite volcanoes are tall, steep cones that produce explosive eruptions. Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Can you consider a mountain as a volcano and can you consider a volcano as a mountain too explain?

Volcanoes are mountains but they are very different from other mountains; they are not formed by folding and crumpling or by uplift and erosion. A volcano is most commonly a conical hill or mountain built around a vent that connects with reservoirs of molten rock below the surface of the Earth.
