Igneous rock.
When magma cools and solidifies, it becomes igneous rock.
Igneous rock is formed when molten magma cools and solidifies. As the magma cools, it hardens and crystallizes, creating igneous rock. This process can happen underground or on the Earth's surface, depending on where the magma cools.
Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
A piece of country rock that breaks off and becomes entrapped in a body of magma is called a xenolith.
It will for an intrusive igneous rock. They usually take longer to cool and have more coarse grains.
Your question as phrased is unclear. I will proceed to answer both interpretations I have of your question. Note: When magma crystallizes, it forms igneous rocks. 1) What is the change of state when magma forms from igneous rock? - Melting. Rocks are the solid state of matter and magma is the liquid state (although it can be a very viscous liquid). Changing something from solid to liquid is melting. 2) What is the change of state when magma crystallizes to form igneous rocks? - Solidification/Freezing. Magma becomes too cold to continue in a liquid state, it solidifies and crystallizes into solid igneous rocks: freezing.
When magma crystallizes, igneous rocks are formed. The type of igneous rock that is formed depends on the chemical composition of the magma and the rate at which it cools.
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
It becomes an igneous rock.
They are rocks formed from magma that cools and crystallizes on the earth surface.
That entirely depends on what type of magma it is and under what conditions it crystallizes. If you are looking for a general rock type, the answer is igneous, but that's very general.
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
Olivine typically crystallizes at temperatures between 1,200 to 1,400 degrees Celsius, while calcium-rich plagioclase feldspar crystallizes at slightly lower temperatures between 900 to 1,200 degrees Celsius from magma.
When magma cools and solidifies, it becomes igneous rock.
when magma cools slowly it becomes extrusive igneous rock
Yes, if magma crystallizes below Earth's surface it will form igneous rocks like granite or diorite. These rocks are known as intrusive igneous rocks, as they formed from magma that cooled and solidified within the Earth's crust.
The mineral that crystallizes first from magma is olivine. Olivine has a relatively high melting temperature compared to other minerals, so it is among the first to solidify as magma cools and begins to solidify.
