A metamorphic rock will have certain minerals and what?
crystals
Metamorphic rocks in which minerals are NOT aligned within the rock are called?
Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.
Metamorphic rocks with a banded appearance due to the alignment of minerals are?
its foliated
What is a metamorphic rock with parallel lines?
Schists are metamorphic rocks with parallel alignment of minerals.
Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as?
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.

What is a mineral alignment?
A mineral alignment is a layered arrangement of firmly joined crystals of minerals; the minerals are aligned in layers or bands.
Metamorphic rocks with a banded appearance due to the alignment of minerals?
its foliated

its foliated
What type of metamorphic texture has no banding?
No banding or alignment of a metamorphic rock's minerals would be consider non-foliated.
What is a metamorphic rock with parallel lines?
Schists are metamorphic rocks with parallel alignment of minerals.
What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?
Heat is one condition that is required to form parallel alignment of minerals sometimes found in a metamorphic rock. The other condition is pressure.
What determines the size of a minerals crystals?
The rate at which magma cools determines the size of the mineral crystal.

Is glass metamorphic?
Crystals are the form that minerals take upon solidification. Metamorphic is a term used to describe a rock that undergoes a chemical or mineral transformation from heat or pressure. New crystals can form in rock undergoing metamorphosis, but the crystals themselves are not considered metamorphic.
How big are the particles in metamorphic rock compared to those in sedimentary rock?
If by particles you mean the size of the crystals, then the crystals in metamorphic rock are often larger than in the sedimentary rock. High heat and pressure can cause the minerals to recrystallize. This would be the case in the metamorphosis of limestone (sedimentary) to marble (metamorphic).
