Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth.
Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.

What unique factor about the arrangement of mineral crystals occurs in many metamorphic rocks?
Foliation
How would you know the difference between igneous and sedimentary and metamorphic rock?
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.
What is metamorphic rock in which mineral crystals are arranged in parallel layers or band?
They are called foliated metamorphic rocks.
Which two of the three rock types appear to be made primarily of intergrown crystals?
Igneous and metamorphic rocks.
Is metamorphic rock generally soft rock or hard rock?
Comparatively hard, due to larger interlocking crystals and a higher density than most igneous/sedimentary rocks
What unique factor about the arrangement of mineral crystals occurs in many metamorphic rocks?
Foliation
Do non-foliated metamorphic rocks contain bands of crystals?
All rocks except volcanic or tectonic glasses have crystals. Therefore all metamorphic rocks have crystals, however in lower metamorphic environments these crystals may remain microscopically small.
How are foliated metamorphic rocks different from nonfoliated metamorphic rocks?
Foliated are made of interlocking crystals, non-foliated are not.
Do metamorphic rocks contain lectures crystals?
yes
Why do sedimentary and metamorphic rocks have bands of colors?
they have more crystals
What do the crystals in metamorphic rocks look like?
they are put together and squated

Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a texture?
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a texture.?
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
The crystals of many metamorphic rocks are aligned in bands as a result of?
heat and pressure
Metamorphic rocks that are non foliated usually have?
High density, hardness, and larger crystals.
What is metamorphic rock in which mineral crystals are arranged in parallel layers or band?
They are called foliated metamorphic rocks.
