Understanding Minerals

The video tutorial explains what constitutes a mineral, emphasizing its characteristics: being solid, natural, inorganic, and having a defined chemical composition. It differentiates minerals from other solids, such as man-made objects and organic substances like coral. The tutorial further elaborates on the crystalline structure of minerals, highlighting how their chemical composition leads to crystal formation.

What is a mineral according to its definition?

• A solid, artificial, inorganic substance with a defined chemical composition
