The type of underground magma formation that is usually dome-shaped is called a "laccolith." Laccoliths form when magma intrudes between layers of rock and causes the overlying strata to bulge upward, creating a dome-like structure. This occurs typically in sedimentary rock layers, resulting in a rounded, uplifted formation that can sometimes be seen at the surface.
What else can I help you with?
As magma moves towards the surface of the Earth it may cool creating underground rock formations It may also pool into deep underground reservoirs called?
magma chambers. These reservoirs can hold large volumes of magma and are important in the formation of volcanic eruptions.
What is a large bowl shaped formation that ocurrs when the top of a volcano falls into the magma chamber?
A caldera is a large bowl-shaped formation that occurs when the top of a volcano collapses into the emptied magma chamber beneath it. This can happen during a volcanic eruption when the magma chamber is emptied, causing the structure above it to collapse inward.
Which step is part of the formation of a batholith?
The intrusion of magma from deep within the Earth's crust into surrounding rocks is a crucial step in the formation of a batholith. As the magma cools and solidifies underground, it forms a large, dome-shaped mass of igneous rock. Over time, erosion exposes the batholith at the Earth's surface.
What is subterranean magma?
Subterranean magma is molten rock located beneath the Earth's surface. It is produced by the melting of rock in the Earth's mantle and can sometimes rise to the surface in volcanic eruptions. Magma plays a key role in the formation of igneous rocks and the Earth's geologic processes.
What name is given to molten rock underground?
Magma is a type of molten rock underground. Hope this helps. :)

How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.

What does not affect the formation of Magma?
Star Wars Movies do not affect the formation of magma.
What is a geological event in which magma does not form lava?
A plutonic geological event involves the formation of magma beneath the Earth's surface that cools and solidifies before reaching the surface. This process results in the formation of intrusive igneous rocks like granite and gabbro.
Is felsic magma eruptive?
Not usually. Because it is so viscous, felsic magma does not erupt as easily as mafic magma. While eruptions of felsic magma do occur, most felsic rocks are intrusive, meaning they solidify underground.
A chamber underground containing magma?
A magma chamber.
