Parts of a volcano |
|
A volcano is made up of a vent, a pipe, a crater, and a cone. The vent is an opening at the Earth's surface. The pipe is a passageway in the volcano. The magma rises through it to the surface during an eruption. The crater is a bowl-shaped depression at the top of the volcano where volcanic materials like, ash, and lava are released. |

Solidified lava, ashes, and cinder form the cone. Layers of lava, alternate with layers of ash to build the steep sided cone higher and higher. |
