Answer :
The type of rock that has a ribbon-like texture with crystals is called gneiss (pronounced like nice).
Gneiss is a type of metamorphic rock that forms from the metamorphism of sedimentary or igneous rocks. It is characterized by its banded or foliated texture, which is the result of the alignment of mineral grains during the metamorphic process. These bands can alternate between different colors and compositions, giving the rock a striped appearance. The presence of visible crystals within these bands is due to the high temperatures and pressures that facilitate crystal growth and segregation of minerals.
The formation of gneiss typically occurs deep within the Earth's crust where temperatures and pressures are sufficient to cause recrystallization and foliation. The minerals that make up gneiss can include quartz, feldspar, mica, and others, depending on the original rock from which the gneiss formed.
Gneiss can be distinguished from other banded metamorphic rocks, such as schist, by its coarser texture and larger crystals. Schist, while also banded, tends to have smaller, flaky mineral grains that are oriented in a parallel fashion, giving it a different texture from gneiss.
In summary, gneiss is the correct answer for a rock type that exhibits a ribbon-like texture with visible crystals, indicative of its metamorphic origin.
I’m pretty sure its gneiss but I might be wrong. Let me know and have a good rest of your day!
