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 else can I help you with?
What is it called when magma hardens in a volcanoes pipe?
a volcanic neck forms when magma hardens in a volcano's pipe and is later exposed.
What rocks form when magma cools and hardens?
Igneous rock is what forms when magma cools and hardens.
What forms when magma hardens in a pipe?
a volcanic neck
What forms when magma hardens in a volcane pipe and is latter exposed?
A volcanic plug. Frequently when glacially eroded these plugs form crag and tail feature.
Forms when magma hardens in a volcano's pipe?
a volcanic neck
What rocks forms when magma or lava cools or hardens?
Basalt
Which igneous rock forms when basaltic magma hardens?
Intrusive rock
Rocks forms when magma or lava cools and hardens?
Igneous rock.
When magma hardens and comes to the earths surface what is it called?
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.
What kind of rock forms when magma or lava cool and hardens?
Igneous rocks
What do you call a rock that forms when magma hardens beneath earth's suface?
The rock that forms when magma hardens beneath the Earth's surface is called an intrusive igneous rock. Examples include granite and diorite.
Magma that hardens vertically underneath the surface will form a sill?
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
