Magma is molten rock that comes from a layer miles beneath the Eart's crust.
When underground pressures force magma upward, it "intrudes" into fissures within the solid rock, separating the layers of rock with "intrusive magma" that does not reach the surface.
When magma erupts out of a volcano, it is "extrusive" and forms either "lava" that flows onto the ground, or "ejecta" that explodes into the air (before falling to the ground as volcanic ash).
Intrusion or extrusion of magma produces "igneous" rock, which very different from rock which is produced by dissolved "sediments" accumulating at the bottom of rivers, or "metamorphic" rock which changes its shape and internal structure due to extreme pressures.
What else can I help you with?
Is magma extrusive or intrusive?
Magma can be either extrusive or intrusive. Extrusive magma forms on the Earth's surface during volcanic eruptions, while intrusive magma forms below the surface and cools slowly to create intrusive igneous rocks.
Does intrusive have lava or magma?
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.
What is intrusive?
Intrusive activity is when magma in the mantle or crust starts to cool and crystallize. Igneous rock forms from the crystallization.
What is igneous rock formed from magma below Earth's surface is called?
It is called an intrusive igneous rock.
Is garnet intrusive or extrusive?
Garnet is typically an intrusive igneous rock. It forms deep within the Earth's crust from the cooling of magma.

What is igneous rock formed from magma?
An igneous rock formed from magma is intrusive.
What type of magma is closer to intrusive rocks?
magma can be classified into two,magma of granitic composition(originates from lower continental crust) and magma of basaltic composition (which originates from upper mantle).Both can form intrusive rocks.
How does intrusive rock form?
intrusive rock froms when magma cools or hardens underneath the earth. :)
What is intrusive?

What is a igneous rock formed from magma called?
intrusive
What is igneous rock formed from magma below Earth's surface is called?
It is called an intrusive igneous rock.
How is intrusive rock form?
Intrusive rocks are formed by the cristalization and cooling of magma deep inside the Earth.
Is intrusive rock is also called platonic rock?
No, intrusive rock is not also called platonic rock. Plutonic rock is another name for this type of rock, which is produced by magma.
What is magma called when cooled slowly?
It will convert from magma to some form of intrusive igneous rock.
