What is a Volcanic Neck?
Practice Version
Volcanic Neck:
Hardened magma in a volcanos pipe. Volcanic neck. A volcanic neck is a column of solidified lava or rock that was once the conduit for magma in a volcano.
Example:
Imagine trying to squeeze out the last bit of toothpaste from a nearly empty tube, but it just won't budge. This situation is similar to a volcanic neck, where hardened magma gets stuck in a volcano’s pipe. Just as dried toothpaste clogs the opening of the tube, preventing any more paste from coming out, hardened magma solidifies in a volcanic pipe, creating a blockage that remains even after the rest of the volcano erodes away.
