What are the similarities and differences between rocks and minerals?
Both are solid, inorganic, naturally-formed substances. However, there are mostly differences, like their uses, structure, and color.
For example, minerals usually have a shape for a structure and are usually the same color, whereas rocks have no definitive shapes. Another difference is the presence of fossils. Rocks sometimes contain fossils, but no minerals have fossils.
Minerals aid in bone and tooth foundation, blood coagulation and muscle contraction. Some of them are also needed for nutrition by humans. To contrast, rocks help give shelter and foundation, but yield little to no health benefits. Lastly, rocks have no definite chemical composition, but minerals do.
