A metamorphic rock can become an extrusive igneous rock through a process called partial melting. When metamorphic rock is subjected to high temperatures and pressures, some minerals within the rock may melt while others remain solid. The melted minerals can then rise to the surface through volcanic activity and cool quickly, forming an extrusive igneous rock. This process is known as anatexis, and it can result in the formation of rocks such as rhyolite or andesite.
What else can I help you with?
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
How does a extrusive igneous rock turn into a metamorphic rock?
Extrusive igneous rocks can turn into metamorphic rocks through the process of regional metamorphism, where they are subjected to high temperatures and pressures deep within the Earth's crust. This causes the mineral composition and texture of the rock to change, resulting in the formation of a new metamorphic rock.
Is basalt metamorphic?
Yes. Basalt is an extrusive mafic igneous rock.
Is pumice a metamorphic rock?
No, pumice is not a metamorphic rock. It is actually a type of igneous rock that forms from volcanic eruptions when frothy lava cools rapidly and traps gas bubbles inside, resulting in its characteristic porous texture. Metamorphic rocks are formed through the transformation of existing rocks under heat and pressure.
Which of Slate Granite Shale or Pumice is classified as a sedimentary rock?
Slate, granite, and shale are classified as metamorphic or igneous rocks, while pumice is classified as an igneous rock. Sedimentary rocks are formed through the deposition and solidification of sediment.
Can a metamorphic rock become a extrusive igneous rock?
Yes because, when it melts and cools off then, it becomes an igneous rock.
Is basalt a igneous metamorphic or sedimentary rock?
Basalt is an extrusive igneous rock.
Is rhyolite a metamorphic rock?
No. Rhyolite is an extrusive igneous rock.
Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
Is schist an intrusive or extrusive rock?
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
Can a A metamorphic rock become an extrusive igneous rock?
a metamorphic rock is formed when it is under great heat and pressure and after some time it forms magma. then the mama comes out through volcano and becomes hard , this rock that is formed is known as extrusive igneous rocks.
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
Is a metamorphic rock intrusive or extrusive?
It is neither. Intrusive and extrusive are terms used to describe igneous rock.
How can an igneous rock become a metamorphic?
A metamorphic rock can become a igneous rock by melting and cooling
Is rhyolite a igneous rock or metamorphic rock?
it is Igneous.actually it is the extrusive counterpart of Granite
When molten rock undergoes crystallization above ground what type of rock results?
Extrusive igneous rock is the result of above ground crystallization.
Is marble an extrusive or an intrusive rock?
Neither. The terms intrusive and extrusive apply to igneous rocks; marble is metamorphic.
