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.
Is this a description for gneiss rock can be made from granite wavy bands of dark and light layers?
Yes, that description fits gneiss rock. Gneiss forms from the metamorphism of granite or other rocks, resulting in distinct wavy bands of dark and light mineral layers. This banding is a key characteristic of gneiss and helps distinguish it from granite.
When is a mineral is discribed as fluorescent?
A mineral is described as fluorescent when it emits visible light when exposed to ultraviolet (UV) light. This phenomenon occurs due to the mineral absorbing UV radiation and re-emitting it as visible light. Fluorescence is often used as a diagnostic tool in mineral identification.
What does the fluoresence of a mineral mean?
The fluorescence of a mineral refers to its ability to emit visible light when exposed to ultraviolet light. This property can provide information about the mineral's composition, impurities, or crystal structure. Fluorescence is commonly used in mineral identification and research.
What is the way the surface of a mineral reflects light called?
The way the surface of a mineral reflects light is called luster. Luster describes how light is reflected off the surface of a mineral, and it can be categorized as metallic or non-metallic.

How could you distinguish pumice and granite?
Granite is a dense, non-porous rock with visible mineral grains. Pumice is a light rock filled with holes left by gas bubbles and generally no visible grains.
What is a way a mineral appears?
Minerals appear in many different ways. Opaque minerals do not allow light to pass through them. Isotropic minerals allow light to pass through it the same way no matter how the mineral is held. Anisotropic minerals reflects light depending up how the grains lay.

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.
Do smooth muscle have alternating dark and and light bands on them?
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.
Many stars together create cloudy bands of light. What is the prepositional phrase?
create cloudy bands of light
What minerals make light bands?
Light bands in minerals, also known as iridescence, are typically caused by the interference and diffraction of light as it passes through thin layers within the mineral. Examples of minerals that commonly exhibit iridescence include opal, labradorite, and pearl. This optical phenomenon results in a play of colors that change depending on the angle of observation.
What type of rock texture results when extreme pressure cause mineral 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.
Are there supposed to be light bulbs in a parallel circuit?
Yes, light bulbs can be powered by a parallel circuit.
What mineral gives off ultraviolet light?
The mineral that gives of ultraviolet light is Quratz
What is the light that shines on music bands called?
a stage-light
