Quartzite is derived from sandstone.

Front

What parent rock does slate derive from?

Front

What is the difference between foliated and nonfoliated metamorphic rocks?

Back

Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while nonfoliated metamorphic rocks do not.

Front

Give an example of a nonfoliated metamorphic rock.

Back

An example of a nonfoliated metamorphic rock is marble.

Front

What is the process of lithification?

Back
