What type of volcanic structure is Shiprock, New Mexico, and how did it form?

What will be an ideal response?


Shiprock is a volcanic neck. When a volcano becomes inactive, congealed magma often becomes preserved in the feeding conduit of the volcano as a crudely cylindrical mass. Over time, all volcanoes will succumb to forces of weathering and erosion. Over time, the rock occupying the volcanic conduit, which is highly resistant to weathering, may remain standing above the surrounding terrain long after the cone has been worn away.
