What do you mean by volcano write different types of volcanoes?

Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.

What are the three main types of volcanoes and how do they differ?

There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.

Why do volcanoes differ in size and shape?

Volcanoes come in different sizes and shapes. The overall size of a volcano is determined by the total volume of lava that has erupted. The shape of a volcano is largely determined by the type of lava that has erupted, and importantly, its viscosity. Viscosity is a fluid’s resistance to flow.

What are the different types of volcanoes based upon the frequency of eruptions illustrate the different landforms created by volcanoes?

Based on frequency of Eruption:

  • Active volcanoes: They erupt frequently and mostly located around Ring of Fire.
  • Dormant Volcano: These are not extinct but have not erupted in recent history.
  • Extinct or inactive volcanoes have not worked in distant geological past.

What are different types of volcanoes on the basis of eruption and periodicity?

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

What are the different types of volcanoes based on its appearance and structure?

What are the different types of volcanoes based on their shape describe each?

Different Types of Volcanoes

Type of Volcano Shape Height
Cinder Cone, AKA Scoria Cone Symmetrical cone Up to 1,200 feet (370 meters)
Shield Tall and broad Up to over 30,000 feet (9,000 meters)
Composite, AKA Strato Tall, steep, and symmetrical Up to 8,000 feet (2,400 meters)
Lava Dome Dome Up to 330 feet (100 meters)

What are the three factors to consider in identifying the category of a volcano?

The composition of volcanic products. The variety of volcanic eruption types. The geometry of the vent. The environment into which the volcanic products are erupted.

Why are some volcanic eruptions quiet and others explosive?

Why are some volcanic eruptions quiet and others explosive? Volcanoes erupt explosively or quietly, depending on the characteristics of the magma. Magma can vary in viscosity, the resistance to flow. Magma with high viscosity is thick and resists flowing.

What is volcano classify them on the basis of their frequency of occurrence?

On ​the basis of frequency of eruption, following are the types of volcano: 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.

What are some examples of different types of volcanoes?

1 Cinder cones. Cinder cones are the simplest type of volcano. 2 Composite volcanoes. St. Helens and Mount Rainier in Washington. 3 Shield volcanoes. Some of the largest volcanoes in the world are shield volcanoes. Loa on the island of Hawaii– two of the world’s most active volcanoes. 4 Lava domes. of Katma Volcano, Alaska.

Why is it important to identify a type of volcano?

Identifying a type of volcano helps predict the kind of eruption to expect from it. The composite volcano, when dormant, is generally a beautiful and impressive mountain. However, eruptions are particularly intense. As magma rises to the eruption point, it tends to get clogged due to high viscosity.

What are composite volcanoes made of?

Composite Volcano Composite volcanoes are steep-sided volcanoes composed of many layers of volcanic rocks, usually made from high-viscosity lava, ash and rock debris. These types of volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that give rise to the name.

What are some famous volcanoes in the world?

Mount St. Helens (USA), Mauna Loa (Hawaii), Mount Cotopaxi (South America), Mount Pinatubo (Philippines) are some famous volcanoes in the world. There are four types of volcanoes based on the nature of their eruption and the kind of lava they release – cinder cone, composite, shield, and lava dome volcanoes.
