If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
Why do minerals change composition as they undergo metamorphism?
The minerals in the rock have been realigned into parallel bands in response to pressures exerted on the rock from a particular direction. The banding forms perpendicularly to the direction of the force.
Does limestone have layers or bands?
I don't know... Maybe bands..??..??..?? Both is a possiblitly
A metamorphic rock with visible layers or bands is said to be what?
Visible layers or bands in metamorphic rock is designated as 'foliation' and the rock is said to be 'foliated'.
What is the description of foliated?
A rock with minerals aligned into bands or layers.
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.
If a rock has bands of light and dark layers it is what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.

What type of rock texture results when extreme pressure causes minerals in metamorphic rock to realign or when minerals separate out into dark and light bands?
I do believe that the answer is "foliated". However I am not positive, but I do know that... Banding is another word for foliation, which is the grouping of certain minerals with the rock forming parallel bands that are perpendicular to the pressure that causes its formation. Banding of different minerals give some metamorphic rocks a striped appearance, involving the segregation of light and dark minerals into layers. Good luck with your question and I hope that this information has helped.

How can you determine if a rock is foliated or nonfoliated?
You can determine because there is texture differences. Also, foliated rocks have visible layers or elongated grains of minerals. Nonfoliated does not have distinct layers or bands.
Why do bands of minerals develop in most rocks?
It's because of foliation. Foliation is defined as the arrangement of a set of minerals in parallel, sheet-like layers that lie perpendicular to the flattened plane of a rock.

What happen to rock when metamorphism takes place?
It is altered physically by pressure and heat and can align the existing minerals into layers or bands called foliations; new minerals may be formed from the minerals that existed before the metamorphism; aqueous solutions between rock particles are squeezed out; and existing minerals may recrystallize.
