There is always more pressure and higher temperature under the Earth's surface. In the root of a mountain chain or near a volcano these forces will be enough to change shape of the strata and the minerals it is made of. Sedimentary rock which has been near such forces often looks as if a giant had twisted it and heated it over a fire. Examples of metamorphic rock:
- Marble a metamorphic rock formed from limestone.
- Slate is a metamorphic mudstone or shale.
- Quartzite is metamorphic sandstone.
The recrystallisation of minerals after heating generally causes the destruction of any fossils the rocks might have contained.
