What are the main features of a volcano?

The main features of a volcano include the magma chamber, vents, craters and slopes. The diagram below shows the main features of a volcano. The magma chamber is a large underground pool of magma. Under pressure, the magma in the chamber can rise up the main vent, which is the central tube through the volcano.

What are the three main parts of a volcano Class 7?

The three main parts of a volcano are the chamber, the vent, and the crater. The chamber is where the magma is stored.

What are the features formed by volcanic eruptions Class 7?

Answer: Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas.

What is volcano Class 7 short?

A volcano is a vent from which a combination of melted rock, solid rock debris and gas erupts. It has a reservoir of molten material below the surface (magma chamber) called magma, and when this magma rises to the surface, it is called lava.

Where are the volcanoes found Class 7?

Answer: Most of the active volcanoes are located in the Pacific Ring of Fire. This is a circular belt around the Pacific Ocean. The ring of fire coincides with the edges of the Pacific Plate.

What are the 5 main types of volcanoes?

The five types of volcanoes we’ll explore are:

  • Cinder Cone Volcanoes.
  • Complex Volcanoes.
  • Composite/Strato-Volcanoes.
  • Shield Volcanoes.
  • Spatter Cone Volcanoes.

The diagram below shows the main features of a volcano. The magma chamber is a large underground pool of magma. Under pressure, the magma in the chamber can rise up the main vent, which is the central tube through the volcano. Volcanoes typically have a bowl-shaped basin at the top of the volcano, known as a crater.

What is a volcanic?

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging , and most are found underwater.

What is volcanic action?

Volcanic action was often attributed to chemical reactions and a thin layer of molten rock near the surface. See also

Can a volcano have more than one opening around the vent?

Volcanoes can have more than one opening around the main vent. These are called cones and fumaroles. These are fractures in the volcano that open up to also release volcanic material and volcanic rocks.
