Question

Which minerals of about the same size growing from the end of the steam?

Answer 1

Answer:

The material that was displaced into the mantle during formation of the iron core contained abundant oxygen, silica, magnesium, iron, aluminum, and calcium (plus smaller quantities of a range of other elements) and under the pressures and temperatures that prevail there, chemical reactions (following the laws of thermodynamics) produce compounds that are known as olivine and pyroxene.  During formation of the crust, other compounds, in particular feldspars and quartz were common reaction products.  The atoms and molecules in these compounds are present in compound-specific proportions, and they are not randomly distributed.  Instead, they show very specific geometric arrangements. These compounds that make up the crust and mantle are commonly known to us as minerals.

Minerals, the building blocks of rocks, are inorganic solids with a  specific internal structure and a definite chemical composition (varies only within a narrow range).  They can form under a variety of conditions, such as:

A) during the cooling of molten materials (steel, from lavas, igneous rocks).

B) during the evaporation of liquids (salt, sugar, reference to evaporites)

C) the cooling of liquids (saturated solution)

D) at high temperatures and pressures new crystals may grow in solid materials (diamonds from coal, metamorphism
