A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock.
In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
What else can I help you with?
What rock melts then hardens again?
Metamorphic rocks can melt under high temperatures and pressures, forming magma. When this magma cools and solidifies, it forms igneous rocks. This process is known as migmatization.
How does a metamorphic rock form into magma?
Metamorphic rock could become magma by collisions involving an oceanic plates. During subduction,any rock carried on the plate would return to the mantle and melt,forming magma
How does a metamorphic rock turn into a igeneous rock?
When metamorphic rock is deposited deep down in the earth, due to pressure and heat, it could be turned easily to lava. When this lava gets heated up the more, due to convection of heat it is force to come out. It cools off on the earth surface as igneous rock.
When a metamorphic rock melts and turn into lava is conserved?
When a metamorphic rock melts, it transforms into magma rather than lava, as lava refers specifically to magma that has erupted onto the Earth's surface. During this melting process, the minerals in the rock may undergo changes, but the overall mass is conserved according to the law of conservation of mass. Once the magma reaches the surface and erupts, it cools and solidifies into igneous rock, completing the rock cycle. Thus, while the form of the material changes, the total mass remains constant throughout these processes.
What is determined by how magma cools and where it cools?
Its texture.
What are the changes of the state that happens when metamorphic rock changes into magma?
Solids become liquids. A phase change.
When magma cools above the earth's surface it forms?
metamorphic rock
How do metamorphic rocks change into igneous rock?
The metamorphic rock melts into magma then cools into igneous rock
How do igneous rocks change into metamorphic rocks?
The metamorphic rock melts into magma then cools into igneous rock
How can a metomorphic rock become an igneous rock?
Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. As the lava cools it hardens and becomes igneous rock.
How does the metamorphic rock change into a igneous rock?
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
How does a metamorphic become magma?
Extreme heat.
Do sedimentary rocks melt and become magma?
No. It's the Metamorphic rocks that melt and become magma.
What does magma become when it cools and hardens?
rock
What kind of rock changes to magma after melting?
metamorphic rock
How does a metamorphic rock become magma?
Extreme heat.
How can metamorphic rock become magma?
If the metamorphic rock becomes hot enough it can melt.
