Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow).
To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.

Where do intrusive igneous rock form?
They form underground from the cooling and solidification of magma.
What type of rock can only be formed deep underground?
metamorphic
What Magma and lava can both solidify to produce?
They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
What must be true for metamorphism to occur?
the process must take place underground~ apex
How can you get different igneous rocks from the same magma body?
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
What type of rock can only form deep underground?
Metamorphic
What type of rock can form deep underground?
Metamorphic
Where do intrusive igneous rock form?
They form underground from the cooling and solidification of magma.
Does magma form when rock begins to melt?
Yes. Magma is underground molten rock.
What rock Can only form underground?
What type of rock is formed from magma that hardens underground?
What are rocks that form when magma cools underground?
A pluton is a body of rock formed from the cooling of magma under the surface.
What rock would form if sandstone was deeply buried and had heat and pressure making it recrystallize?
The metamorphic rock quartzite would form due to the heat and pressure.
How do veins form?
pure metals that crystallize from hot water solutions underground often form veins.Veins form when rock collides with another rock and the rock that collide pushes the other rock untill only a little bit of it is left
What type of rock can only be formed deep underground?

They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
Which is a factor that prevents us from finding the Precambrian fossils?
most rock form that era are deeply buried.
