1. What are minerals?​

Answer 1

Answer:

Minerals are defined as solid, inorganic, naturally occurring substances with a definite chemical formula and general structure. Almost all chemical elements in the Earth's crust are associated with at least one mineral. They vary in color, hardness, density, crystal form, crystal size, transparency, composition, location, and abundance. Some minerals are radioactive (uranophane), while others are magnetic (magnetite). Some are uncombined elements, such as gold, silver, sulfur, bismuth, copper and platinum. Certain minerals, such as fluorite (calcium fluoride), glow with a vibrant luminescence after exposure to ultraviolet light. Feldspar (a potassium aluminum silicate) and quartz (silicon dioxide) are the most abundant minerals found in the Earth's crust. Mankind has coveted many minerals and gemstones due to their striking, beautiful colors. Some specimens of opal exhibit iridescent, rainbow-like colors within their crystals, while some specimens of the gemstone tourmaline show progressions of watermelon-like green to pink color from one side of a crystal to another. Although interesting, a few minerals are deceiving; many amateur prospectors have been tricked into thinking they have found gold, but have instead found pyrite (iron disulfide), otherwise known as "Fool's Gold" due to its uncanny resemblance to the precious metal. Diamond, the hardest natural substance found on Earth, has long been prized as the most desirable of all minerals due to its stunning interaction with light. Most diamonds, though, are impure and not suitable as gemstones; instead, they find industrial use as cutting tools, and are even made synthetically to meet this demand.

Answer:

Almost all chemical elements in the Earth's crust are associated with at least one mineral. ... Some are uncombined elements, such as gold, silver, sulfur, bismuth, copper and platinum etc..

Minerals are substances that are formed naturally in the Earth. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes. The study of minerals is called mineralogy. A mineral can be made of single chemical element or more usually a compound.

Some types of minerals

• Iron ore.
• Silver.
• Gold.
• Cobalt.
• Bauxite.
• Lithium.
• Zinc.
• Potash.

Types of minerals

There is 1 pending change awaiting review. There are three different types of rocks: Igneous, Sedimentary, and Metamorphic. The difference between each type is in how they are formed.

Common minerals

The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.
