Answer:
Different types of rocks have different chemical composition.
Explanation:
Rock can be distinguished from each other by their chemical composition which is a product of the minerals they contain.
- A rock is an aggregate of minerals.
- Different suites of rocks have their inherent mineralogical composition and facie.
- This is because, these rocks form under different types of conditions from time to time.
- Igneous rocks form from molten rocks, sedimentary rocks form from pre-existing rocks and metamorphic rocks for under elevated temperature and pressure conditions.
- All these conditions plays important roles in the differentiation of minerals in the rock.
