Metamorphic rock is a type of rock that is "morphed" or changed in to another rock. These rocks could have once been sedimentary or igneous rocks. Metamorphic rock is formed when the rock is under lots of pressure and heat builds up and melts the rock.
Foliated Rocks-
When the rocks have parallel layers, they are called foliated. The term "foliated" is from the Latin"leaf." Foliated describes how the flat, thin layers found in most metamorphic rocks. Some examples of foliated rock are slate, schist, shale, and gneiss.

Uses: Metamorphic rocks are used to make floors, counters, statues, buildings, roofing, etc.
Nonfoliated Rocks- Nonfoliated rocks don't have a pattern unlike foliated rocks. Nonfoliated rocks do not have any layers. That way you can tell the difference between foliated and nonfoliated rocks. Some examples of nonfoliated rocks are marble and quartzite.
