Vent

• Opening through which lava erupts

• A type of volcanic rock

Volcanic Cone

• A type of mountain formed by erosion

• A hill formed by volcanic material

• A flat landform created by sedimentation

• A deep valley formed by tectonic activity

Crater

• Basin-shaped depression at the top

• Flat surface with no elevation

• Deep valley formed by erosion

• Mountain peak with a sharp summit

Lava Flow

• Molten rock that flows out of a volcano

• A type of solid rock found in the Earth's crust

• A gas released during volcanic eruptions

• A liquid that cools to form igneous rock

Conduit

• A type of rock formation

• A door which magma travels

• A volcanic eruption

• A type of mineral deposit

Ash cloud

• Mass of tiny volcanic rock fragments, dust, and gases that are released into the air.

• A type of cloud formed by water vapor in the atmosphere.

• A cloud that contains only water droplets and no solid particles.

• A cloud that is formed from smoke and pollution in urban areas.

Summit

• Highest point of the volcano

• Base of the volcano

• Side of the volcano
