2.5 Formation of Minerals – Physical Geology

2.5 Formation of Minerals. In order for a mineral crystal to grow, the elements needed to make it must be present in the appropriate proportions, the physical and chemical conditions must be favourable, and there must be sufficient time for the atoms to become arranged. Physical and chemical conditions include factors such as temperature ...

Mining National Geographic Society

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
