Explanation:
A metamorphic rock is a igneous rock, sedimentary or other metamorphic rock that it have undergone pressure and heat. These causes of metamorphism such as heat more than 200°C (but below the boiling point of the rock) and pressures higher than 300Mpa break down the atoms in the rock’s minerals and recrystalize the rock into something different with many interesting and useful properties.
