EzraGeologists classify metamorphic rocks based on texture, mineral composition, and the degree of metamorphism. Texture refers to the size, shape, and arrangement of minerals in the rock. Mineral composition refers to the specific minerals present in the rock, which can indicate the temperature and pressure conditions under which the rock formed. The degree of metamorphism refers to how much the rock has been changed from its original state.

Geologist classify rocks according to their?
They classify metamorphic rocks according to their parent rock or protolith.
What are the classes of metamorphic rocks?
The classes of metamorphic rocks include foliated rocks, which have a layered or banded appearance due to the alignment of minerals, and non-foliated rocks, which lack a layered structure. Foliated rocks include slate, schist, and gneiss, while non-foliated rocks include marble and quartzite.
Which is a characteristic of all nonfoliated metamorphic rocks?
Lack of banding
What are characteristic of metamorphic rocks?
grayish i think it just looks like rock
What condition change igneous rocks and sedimentary rocks to metamorphic rock?
The conditions needed to change igneous or sedimentary rocks into metamorphic rocks are high pressure, high temperature, and/or chemically active fluids. These conditions cause the minerals in the original rocks to recrystallize and realign, forming new minerals and textures characteristic of metamorphic rocks.
