It needs to have been under these conditions; thermal energy, pressure, or chemical activity. It can have more that one way of those.
Igneous rock is classified as extrusive or intrusive.
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
It is called Non-foliated.
A metamorphic rock.
No. Slag (more commonly called scoria) is an igneous rock.
the recrystallization of unmelted material under high pressure results in Metamorphic Rock
Only sedimentary rock by the weathering, erosion and subsequent deposition of material from the metamorphic rock.
The rock that existed before it is changed into a metamorphic rock is called a protolith.
Slate
The main process would be the melting and re-solidification of the material present in the metamorphic rock.
The original rock to a metamorphic rock is called the protolith.
No
Marble is a metamorphic rock type form. Marble is used as a building material and as sculpture material also.
a Black Rock
Igneous rock is formed by magma cooling and becoming solid. Metamorphic rock is the end result of a process called metamorphism (which means "change in form"). Sedimentary rock is formed by sedimentation of material at the Earth's surface and within bodies of water.
If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.
