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.
A volcanic neck is formed when magma hardens in the volcanoes pipe.
Volcanic Neck or volcanic plug is the type of landform that is created when magma hardens in a volcano's pipe.

Magma that forces its way into rocks and hardens is called intrusion.

If the magma has hardened before being exposed at the surface it would be considered an intrusive igneous rock. It is hardens at or near the surface, it would be called extrusive igneous rock.
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
Igneous rock is formed when hot magma from inside the earth meets the earth's outer crust and eventually cools to form one of the three different types of rock.
a volcanic neck forms when magma hardens in a volcano's pipe and is later exposed.

The magma eventually hardens and becomes rock. That's how Hawaii formed because of the volcanoes that formed it.
Volcanic Neck
Volcanoes are formed through a crack in the earth's surface where magma spills out from inside the earth. When lava spills out of a volcano, it eventually hardens and gives volcanoes their cone shapes.
Igneous rock is what forms when magma cools and hardens.
No. Igneous rock is simply the solid substance left when magma or lava hardens, above ground or below ground.
Igneous rocks are created when magma cools into a solid state.
Volcanoes have magma.
No. A sill forms when magma hardens parallel to the rock layers, which is usually horizontal. When magam hardens vertically, it forms a dike.
