What does 'foliated' mean in relation to metamorphic rocks?

Back

Foliated refers to a texture in metamorphic rocks where minerals are aligned in layers or bands.

Front

What does 'nonfoliated' mean in relation to metamorphic rocks?

Back

Nonfoliated refers to a texture in metamorphic rocks that does not have a layered or banded appearance.

What is the rock cycle?

Back

The rock cycle is the continuous process by which rocks are formed, broken down, and reformed through geological processes.

Front

What type of rock can become a metamorphic rock?

Back

Any type of rock, including igneous, sedimentary, or other metamorphic rocks, can become a metamorphic rock.

Front

What is the role of heat in the formation of metamorphic rocks?

Back

Heat can cause minerals within a rock to recrystallize, leading to changes in texture and composition.

Front

What is the role of pressure in the formation of metamorphic rocks?

Back

Pressure can cause the minerals in a rock to become denser and can also lead to foliation.
