The tunnel that magma goes through to reach the top of a volcano is called a conduit. This conduit is often a vertical pipe-like structure that connects the magma chamber beneath the volcano to the surface.


When magma becomes lava what does it reach?

When magma becomes lava it has reached the very top of the volcano and is out of it on land


What is the tunnel that lava travels to reach the top of the volcano called?

The tunnel through which lava travels to reach the surface of a volcano is called a volcanic conduit. It is a passage that connects the magma chamber below the volcano to the vent at the surface. The lava moves through this conduit under pressure before erupting onto the surface.


What is the process on how magma flows inside and outside a volcano?

First, the magma breaks open rocks underneath the volcano. Then, it flows up through cracks of the volcano. After it is all the way to the top, the volcano erupts. Then the magma and lava flows outside the volcano.

What are the main parts of a volcano and their functions?

The main parts of a volcano include the magma chamber where molten rock is stored, the vent through which volcanic gases and magma are expelled, and the crater at the top of the volcano where eruptions occur. These parts work together to release pressure from within the Earth and allow magma to reach the surface, creating volcanic activity.


Where is the crater of a volcano?

Usually at or near the top. It is linked to the vent where magma erupts.


What does magma that reaches the surface flow out of?

it flows out of the central vent at the top of the volcano


What is the name of the hole at the top of a volcano?

The name of the hollow landform, found at the top of the volcano is called crater.


Where is the crater of the volcano located?

Usually at the top or close to the top. It is linked to the vent (above the vent) where magma erupts.
