well technically the first diamonds were made from magma before the earth was populated with people, but now the only way to make crystals(not diamonds) is from burning graphite, which is the only other substance completely made from carbon, like diamonds. so yes technically crystals are made from magma when it is spewed up from volcanos.
Metamorphic rocks are composed of mineral crystals of various shapes and sizes.
No. Crystallization and solidification of magma forms igneous rock.
No, those are igneous rocks. Metamorphic rocks change due to pressure and heat, but they do not melt.
Yes, the combination of interlocked mineral crystals that form from cooling magma create igneous rock.
it gets hot as it compacts and the magma slowly melts it under extreme heat and pressure
The crystallization of magma results in an igneous rock, but if the magma came from a previous igneous rock that melted, then it does make a metamorphic rock.
no
Sedimentary rocks have layers, not metamorphic rocks.
Foliated rocks are metamorphic rocks that look like they have layers or the appearance of layers. Non-foliated rocks are metamorphic rocks without any foliation.
They are both rocks
Gneiss
foliated metamorphic rocks. The alternating layers are caused by the alignment and segregation of minerals during the metamorphic process, resulting in a banded or layered appearance. Examples of foliated metamorphic rocks include gneiss, schist, and slate.

Igneous rocks, non-foliated metamorphic rocks, and evaporites do not have layers.
Foliated rocks have layers in them. We often refer to the layers as Banding.

foliated
I think they're found in the fossils of dead animals or plants.
