Minerals are fundamental components of rocks and have great economic and commercial significance to humans. Therefore, geologist
s need a set of characteristics to identify and describe what makes an object a mineral versus something synthetic (such as plastic, for example). The criteria that defines matter as a mineral is that it is inorganic, composed of an orderly crystalline structure, solid, naturally occurring, and can be expressed by a chemical formula. Some matter looks very similar to minerals, but does not quite meet the criteria. For example, consider glass and quartz. Both are transparent and can have similar appearance. Glass does not have an orderly internal structure; its silica atoms are randomly arranged. Thus it is not a mineral. Quartz, however, has an organized chemical structure of silica atoms, each surrounded by four oxygen atoms and is a mineral.
The items that are minerals are Quartz
, Charcoal
, Seawater
, Amber
, Granite
, Synthetic diamonds
, Gold nugget.
Explanation:
The mineral is a fundamental part of the rocks and has a great economic and commercial value. They have a set of characteristics that defines them.
They may be classified as inorganic or organic and maybe actually occurring or created artificially. They can be transparent and opaque, some are made of silica, and others are arranged in order of internal composition.
Technology has made it to where you can find or look for almost anyone you can think of at the click of a mouse. Technology has made it easier for people to communicate and meet other people.
