Metamorphic Rocks

Front

What are metamorphic rocks?

Back

Metamorphic rocks are rocks that have been changed from their original form due to heat, pressure, or chemically active fluids.

Front

What is foliation in metamorphic rocks?

Back

Foliation is the alignment of mineral grains in a metamorphic rock, resulting in visible bands or layers.

Front

What is a nonfoliated metamorphic rock?

Back

Nonfoliated metamorphic rocks do not have a layered or banded appearance and are typically composed of a single mineral.

Front

How do metamorphic rocks form?

Back

Metamorphic rocks form from existing rocks (igneous, sedimentary, or other metamorphic rocks) that undergo metamorphism due to heat and pressure.

Front

What is an example of a foliated metamorphic rock?

Back

Slate is an example of a foliated metamorphic rock.

Front

What is an example of a nonfoliated metamorphic rock?

Back

Marble is an example of a nonfoliated metamorphic rock.

Front

What is the process of metamorphism?

Back

Metamorphism is the process by which rocks are transformed by heat, pressure, and chemical processes.

Front

Can metamorphic rocks be formed from all types of rocks?

Back

Yes, metamorphic rocks can form from igneous, sedimentary, and other metamorphic rocks.

Front

What happens to rocks during metamorphism?

Back

During metamorphism, rocks may change in texture, mineral composition, and structure.

Front

What is the difference between foliated and nonfoliated rocks?

Back

Foliated rocks have visible bands or layers, while nonfoliated rocks do not.
