A volcanic neck is a cylindrical mesa composed of basaltic rock and protruding from the surrounding terrain. A volcanic neck forms inside a volcano when the heat and pressure from below are reduced so that the magma inside the volcano's vent solidifies. Over a period of a few hundred thousand years, the surrounding softer earth erodes away, leaving the volcanic neck standing alone.

When magma hardens in a volcano's pipe the result will eventually be a landform called a?
When magma hardens in a volcano's pipe, the result will eventually be a volcanic neck or volcanic plug. This landform is a solidified remnant of magma that once filled the volcano's vent.

What type of landform can be created when magma hardens in a volcanoes pipe?
Volcanic Neck The surrounding rock weathers more easily than the magma in the pipe. The resultant structure will first appear as a low flat protrusion which is slightly elevated from its surroundings. With additional weathering of the surrounding rock, the hardened magma may appear as a tower with possible basaltic columnar structure known as a volcanic plug or volcanic neck.

What is a volcanic conduit called after the conduit has solidified and been exposed by erosion?
A volcanic conduit that has solidified and been exposed by erosion is called a volcanic neck or volcanic plug. These features are made up of solidified magma that once flowed through the conduit of a volcano.

What describes the volcanic neck?
A volcanic neck forms when the magma inside a volcano turns into rock and the outside of a volcano wears away, leaving the spiky-shaped rock magma.
