The volcanic landform that is formed when the more resistant volcanic pipe remains after most of the cone has beeneroded is called a?
volcanic neck
What makes up Ship Rock?
Ship Rock is a unique volcanic neck formation composed mainly of fine-grained volcanic rock called minette, which is rich in potassium feldspar. It was formed from the solidified remains of a volcanic vent that never erupted at the surface. Ship Rock rises 1,500 feet above the desert floor and is one of the most prominent landmarks in the Navajo Nation.
What is a volcanic neck?
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.
Is devil's tower active?
No, Devil's Tower is not active. It is a dormant volcanic neck, formed by the solidified magma of an ancient volcano. There is no current volcanic activity at Devil's Tower.
How is a volcanic neck formed?
A volcanic neck forms when magma solidifies in the vent of a volcano, after the solidification the volcano goes either dormant for an extended period of time or goes extinct. During this period of quiescence the ash around the vent erodes away as well as all the other light material leaving only the spine that was the plug in the vent. This will last the longest as it is very densely solidified magma versus a loose conglomerate of ash on the flanks of the volcano.

What type of rock is shiprock made of?
Shiprock is made of igneous rock, specifically volcanic rock known as minette. It formed from a volcanic neck or throat as magma solidified beneath the surface and was exposed after millions of years of erosion.

What are three features formed by magma?
A batholith, a volcanic neck, and a dome mountain.
Forms when magma cools within earth?
Volcanic neck.
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 the Significance of volcanic neck?
there's diamonds and granite in a volcanic neck
