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.
No. Slag (more commonly called scoria) is an igneous rock.
metamorphic rock
Anthracite is a metamorphic rock commonly called coal ,whose protolith or parent rock is bituminous coal.
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 original rock that undergoes metamorphism to form a metamorphic rock is called a protolith or parent rock.
The original rock that exists before it undergoes metamorphism is called a parent rock or protolith. This parent rock can be any type of rock, such as sedimentary, igneous, or another metamorphic rock, that is subjected to high temperature and pressure to form a metamorphic rock.

No
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.
material that is under extreme heat and pressure and molds together to become a rock
Slate is a common metamorphic rock used for roofing material due to its durability, water resistance, and natural beauty. It is formed from the metamorphism of shale or mudstone.
It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
Quartz sandstone, aka arenite, can form the metamorphic rock called quartzite.
