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.

Is magma the source of all rocks on earth?
No, while all rocks on Earth were molten at one point, most rock types do not form from magma. Rocks that form from magma or lava are igneous rocks. Most of the rocks at Earth's surface are sedimentary. These rocks form from the remains of rock that have been broken own into tiny pieces or dissolved in water. These components eventually settle, usually in a body of water, and are buried and turned to stone. Metamorphic rocks make up a third category. These form from rocks that have been altered under enormous heat and pressure while remaining solid.
How do sedimentary rocks becomes igneous?
Sedimentary rocks, as a rule, must first undergo a change into a metamorphic rock (a process which can take hundred of thousands to millions of years), before they may become molten from subduction processes or contact with a body of magma, whereby the magma would cool and form an igneous rock.
Is a pluton?
A pluton is a large body of igneous rock which has formed underground as rising magma has cooled.
What is an intrusive igneous body is it stock stope or magma chamber or aphanite?
An intrusive igneous body is a mass of igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. Examples include stocks and batholiths, which are large, irregularly shaped bodies, and dikes and sills, which are more tabular. Aphanite refers to a fine-grained volcanic rock and is not an intrusive body itself. Therefore, the correct answer would be stock or magma chamber, but not aphanite.
Can a single magma can produce several different igneous rocks having different mineral compositions?
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.
What are rocks that form when magma cools underground?
Intrusive igneous rocks, such as granite and diorite, form when magma cools underground. These rocks have a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form within the rock. Intrusive rocks are typically found in plutons or batholiths beneath the Earth's surface.
Which of that following is an intrusive igneous body?
A batholith is an example of an intrusive igneous body. Batholiths are large formations of intrusive igneous rocks that form beneath the Earth's surface through the slow cooling and solidification of magma.
What is the solid form of magma body?
The solid form of a magma body is called igneous rock. Igneous rocks form when magma cools and solidifies either underground (intrusive) or on the surface (extrusive). Examples of igneous rocks include granite, basalt, and obsidian.
What is solid form of magma body?
When magma solidifies, it becomes igneous rock.
Why are fossils rarley found in igneous rocks?
Fossils are the remains or traces of animals or plants and are normally found in rocks which used to be sediments at the bottom of a body of water in which they lived or were swept into. None of these living organisms were able to live in molten magma which is what most igneous rocks used to be.
Igneous rock that forms beneath Earth's surface is called?
Igneous rock which solidifies from magma underground is classified as intrusive igneous rock.

How does magmatic differentiation account for variety of igneous rocks?
Magmatic differentiation accounts for a variety of igneous rocks occurring in the same body of rock by:Mixing of magmas from two or more sources.Distinct melting events from a variety of sources.Crystal fractionationPartial melting from the same source.Immiscibility.Assimilation of crustal rock by magma.
What is a mass of rock formed when a large body of magma cools inside the Earth?
A mass of rock formed when a large body of magma cools inside the Earth is called an intrusion or pluton. These formations are referred to as intrusive igneous rocks and can vary in size and shape depending on the depth and cooling rate of the magma within the Earth's crust.
