Lesson Review
PART A Write true if the statement is true. If the statement is false, change the underlined term to make the
statement true.
1. Metamorphic rocks are classified according to their shapes.
2. A foliated metamorphic rock has mineral crystals arranged in bands.
3. The texture of a metamorphic rock refers to the arrangement of its mineral
crystals.
4. Foliated metamorphic rocks usually break along their outer edges.
5. Marble contains large mineral crystals of quartz.
