In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science ...
Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy[n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy ...
Mining. Mining of sulfur from a deposit at the edge of Ijen 's crater lake, Indonesia. Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.
Stone industry.
