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.
What colours is the Planet Jupiter?
dark brown and light brown
Has parallel bands of Dark and light mineral grains?
Yes, parallel bands of dark and light mineral grains are characteristic of certain types of metamorphic rocks, particularly schist and gneiss. This banding, known as foliation, occurs due to the alignment of minerals under directional pressure during metamorphism. The dark bands typically consist of mafic minerals like biotite or hornblende, while the light bands are usually made up of felsic minerals like quartz or feldspar. This texture can provide insights into the geological history and conditions under which the rock formed.
What Wavy bands of light and dark minerals visible in gneiss probably formed from the?
The wavy bands of light and dark minerals visible in gneiss likely formed from the process of high-grade regional metamorphism, where pre-existing rocks (such as granite or sedimentary rocks) were subjected to intense heat and pressure. This metamorphic process causes the minerals to recrystallize and segregate based on their composition, resulting in the characteristic banding. The light bands are typically rich in quartz and feldspar, while the dark bands are often composed of biotite, amphibole, or other mafic minerals. The wavy appearance of the bands can also reflect the dynamic conditions of deformation during metamorphism.
What is a metamorphic that can be made from granite wavy bands of dark and light layers?
A metamorphic rock that can form from granite with wavy bands of dark and light layers is called gneiss. Gneiss is characterized by its foliated texture, which results from the high-grade metamorphism of granite, causing the minerals to realign and separate into distinct layers. The wavy bands typically consist of alternating light-colored quartz and feldspar, along with darker bands of biotite or amphibole. This layering gives gneiss its striking appearance and indicates significant geological processes.
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.
What are the bands on Jupiter?
The bands on Jupiter are areas of alternating light and dark clouds that are caused by differences in the planet's atmospheric composition and temperature. The most prominent bands are the equatorial bands and the polar bands, which are visible in Jupiter's atmosphere.
What is a young salmon covered with dark stripes bands of spots?
Hhi
A bands are dark bands?
Yes, in striated muscle you can think of the "A" bands as the dArk bands and the "I" bands as the lIght bands.
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.
Two muscular tissues that show light and dark bands?
Skeletal and cardiac muscle tissues are both considered as striated, which means that they have light and dark bands.
Combination of alternating dark A bands and light?
The alternation dark and light bands are found in muscles of humans and animals. They give the muscle fibers their striated appearance.
Which proteins form light and dark bands?
In striated muscle fibers, light bands (I bands) are formed by the protein actin, while dark bands (A bands) are formed by the protein myosin. These proteins play a crucial role in the sliding filament theory of muscle contraction.
What property of light producing dark and bright bands on the screen after light passes through two slits?
The property of light responsible for producing dark and bright bands on the screen after passing through two slits is interference. When light waves pass through the two slits and overlap on the screen, they interfere with each other either constructively (bright bands) or destructively (dark bands) based on their relative phase.
Skeletal muscle cells are striated that is they have alternating dark and light bands called repectively?
A and I bands
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.
What causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
