Gneiss is a type of metamorphic rock that often exhibits large intergrown crystals in thin bands. It forms from the transformation of pre-existing rocks under high temperature and pressure conditions, resulting in a banded appearance with distinct layers of different mineral compositions and grain sizes.
metamorphic rock.
Sedimentary rocks have flat layers.
Yes, the other type is a foliate rock with bands of minerals.
Strata refers to the individual layers in sedimentary rock. On occassion, igneous rock can also demonstrate stratification.
Folliated Metamorphic Rock. Example is Gneiss (Banded Gneiss)
The arch is made up of either sedimentary rock or metamorphic rock. Most likely sedimentary because the layers in the arch are distinct, solid bands of color, whereas a metamorphic rocks have swirly bands of color from the emense pressure the rock went through. Another reason the rock might be sedimentary is because the arch opening would not be as large if the rock was metamorphic rock, which can whithstand more erosion than sedimentary rock.

Foliated rock has parallel layers.
metamorphic rock.
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.
Foliated rock
Sedimentary rock.
Sedimentary rocks have flat layers.
That would be sedimentary rock, and (honorable mention) occasionally metamorphic rock.
