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.
If a rock has shiny surfaces or bands of light and dark layers then it is?
The bands of light and dark are classic signs of Gneiss (Gneissose banding), but Gneiss is not necessarily shiny. It may be sparkly, but not shiny. However, a Slate IS shiny, but does not have the pretty banding. Another consideration is Schist, which has similar characteristics to Gneiss. My advise is that if you are classifying a rock that you are looking at, consider the grade of metamorphism, as it certainly is metamorphic. Also consider the mineralogy: what are the light and dark bands? Quartz, Feldspar (light)? Mica (biotite) (dark)? There are many possibilities. The mineralogy will help determine the original sedimentary rock, which you can then use to determine the metamorphic sample you have.
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'.
Metamorphic rock that show layers of dark minerals alternatin with layers of light minerals are classified as?
Foliated is the correct answer!!!
What are the layers or bands on a rock called?
Strata (singular = stratum).

Is this a description for gneiss rock can be made from granite wavy bands of dark and light layers?
Yes. This metamorphic rock can be made from granite; wavy bands of dark and light layers.
If a rock has bands of light and dark layers it is?
It could be foliated metamorphic rock or sedimentary rock, depending on its mineral makeup and method of formation.
Why are mineral bands in metamorphic rocks light and dark colored?
Mineral bands are light and dark colored because they are different types of rock. In the rock cycle different types of rock can stack on top of each other, this can be subducted into the earth near the Mantle where there is enough pressure the rocks can start to melt and change. Because different types of rock metamorphose into different rocks you can have many layers in a type of rock. These can be light or dark colors depending on the rock.
What rock has parallel bands of dark and light mineral grains?
It is a sedimentary rock
What type of rock has light and dark layers?
foliated.
