Geologists 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.
Geologist classify rocks according to their?
They classify metamorphic rocks according to their parent rock or protolith.
How do geologists classify metamorphic rock?
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
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.
Classify metamorphic rocks as foliated or non-foliated?
cats
Which is a characteristic of all nonfoliated metamorphic rocks?
Lack of banding
What are the three main categories into which geologists classify rocks?
The three main categories into which geologists classify rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and lithification of sediments. Metamorphic rocks are created from the alteration of pre-existing rocks due to high temperature and pressure.
What major group does foliated rocks belong?
Foliation is a characteristic of some metamorphic rocks.
How do geologist classify a rock?
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
What is used to classify metamorphic rocks?
texture, color, chemical reactions things like that.
Do geologists classify metamorphic rocks by the arrangement of grains making up the rock?
Yes.
What do scientists classify rocks into what one of the three main categories by?
Scientists classify rocks into three main categories - sedimentary, igneous, and metamorphic - based on how they are formed. Sedimentary rocks are formed from the accumulation and solidification of sediments, igneous rocks are formed from the cooling and solidification of magma or lava, and metamorphic rocks are formed from the alteration of existing rocks through heat and pressure.
