Metamorphic Rocks
Metamorphic rocks are rocks that change over time deep within the earth overtime. Heat from the inner core and pressure from the rocks above will slowly cause the rock to change. A metamorphic before the change is called a parent rock. In this section you will learn all about metamorphic rocks and different types of metamorphic rocks.
Foliated Rocks

Foliation occurs when a rock changes into a metamorphic rock but at the same time gains layers. Gneiss is an example of a foliated metamorphic rock. It has bands circling around allowing it to have layers.

Non-Foliated Rocks
Non foliated rocks are created when a rock changes into a metamorphic rock but at the same time does not gain any layers. This type of rock is just a plain old metamorphic rock without layers to it. An example is Amphibolite.
