Gneiss is generally coarse-grained.
gniess is made of granite
The word that describes the shapes and sizes of grains in a rock is "texture." Texture refers to the arrangement and size of mineral grains in a rock, whether they are fine-grained, coarse-grained, or other specific characteristics.

The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
Texture is the word used to describe a rock's constituent mineral size and arrangement, visible on a freshly fractured surface. Because a rock's surface can be weathered to a smooth or polished surface, the way it feels is not usually included in a description of texture.
Metamorphic.
Yes. Gneiss is a foliated metamorphic rock.
metamorphic
because of the minerals that are mixed in with the gniess during the rock cycle(probably at the igneous stage) reflect light off of themselves

Gniess is Metamorphic.
Granite must be exposed to tremendous heat and pressures in order to transform into the metamorphic rock gneiss.
The word that describes the shapes and sizes of grains in a rock is "texture." Texture refers to the arrangement and size of mineral grains in a rock, whether they are fine-grained, coarse-grained, or other specific characteristics.
Gniess is formed from pre-existing rocks that are subjected intense derectional pressure.

Gneiss is a metamorphic rock formed from the alteration of pre-existing rocks through intense heat and pressure. It typically exhibits distinct bands of alternating light and dark minerals, giving it a banded or striped appearance.
