What are Minerals?
Minerals are natural solid substances found in the earth. They form naturally, have a fixed chemical makeup, and usually have a crystal structure. Examples of minerals include quartz, mica, calcite, gold, and halite.
In simple words, minerals are the natural materials that make up many rocks and are also used in jewelry, industry, and everyday products.
