Minerals are solid, naturally occurring substances found on Earth. They are part of the composition of rocks and often have a crystalline structure.
Minerals can have different physical and chemical properties, such as hardness, luster, color, and chemical composition.
Some minerals are valuable for their use in industry or in the manufacturing of objects, like iron for building structures or gold for making jewelry.
Additionally, minerals play an important role in nutrition and soil formation, as they contain essential nutrients for plants and animals.
