What are the internal parts of a volcano?
The main parts of a volcano include the magma chamber, conduits, vents, craters and slopes. There are three types of volcanoes: cinder cones, stratovolcanoes and shield volcanoes.
What is the thing inside a volcano?
Inside an active volcano is a chamber in which molten rock, called magma, collects. Pressure builds up inside the magma chamber, causing the magma to move through channels in the rock and escape onto the planet’s surface. Once it flows onto the surface the magma is known as lava.
What are the 3 main external parts of a volcano?
Flank – The side of a volcano. Lava – Molten rock that erupts from a volcano that solidifies as it cools. Crater – Mouth of a volcano – surrounds a volcanic vent. Conduit – An underground passage magma travels through.
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 structural features of the 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.

What are physical features of a volcano?
Landform-scale, volcanic geomorphologic features include lava flows and related features (diverse types of scarps, levees, and lava flow surface features); lahars, calderas, the diverse types of cones and related rims, necks, domes, tubes, trenches, fissures and scarps.
