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.
What do metamorphic rocks with a non-foliated texture show metamorphic changes involve?
mineral grains arranging into layers.
A type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.
Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
Is rock with visible layers and no visible mineral crystals likely to be formed from lava hardening on Earth's surface?
Probably not. While layered lava flows are not uncommon, most layered rocks formed from the accumulation and lithification of sediment.

What is a banded mineral?
A banded mineral is a mineral that has grains that are arranged in a particular pattern of flat layers or forms swirls.
When a mineral grains in a metamorphic rock do not form layers the rock has a?
no texture
When mineral grains in a metamorphic rock do not form layers the rock has what texture?
no texture
What type of metamorphic rock is composed of mineral grains arranged in parallel layers?
Foliated.
What is a type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
schist
When mineral grains flatten and line up in layers a metamorphic rock has a?
A schistose texture.
What do metamorphic rocks with a non-foliated texture show metamorphic changes involve?
mineral grains arranging into layers.
Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Nonfoliated
A type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.
What metamorphic has elongated layers?
Regional metamorphism
Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
