Why are there more silicate minerals than non-silicate minerals?

Answer 1

Next to oxygen , which is the most abundant element in the crust of the Earth, silicone is second. So you would expect to find the most abundant compounds to be made from the most abundant elements. Note that carbon , the basis for hydrocarbons (organics) is way down the list. It is fifteenth.
Oxygen (O) 461, 000 Mg/ Kg - 46 %
Silicon (Si) 282, 000 - 28 %
Aluminum (Al) 82 ,300 - 8 %
Iron (Fe) 56, 300 - 6 %
Calcium (Ca) 41, 500 - 4 %
Sodium (Na) 23, 600 - 2 %
Magnesium (Mg) 23, 300 - 2 %
Potasium (K) 20, 900 - 2 %
(The sub total here is 98%)
Carbon (C) 200ppm - 0.02 %
Nitrogen (N) 20ppm - 0.002%
(ppm is parts per million)

Answer 2

As others have said, obsidian is a glass made from the rapid freezing of a silicate liquid (a magma). A glass is classified as a non-crystalline solid - the substance freezes into place in the same lack of order that existed in the liquid (a liquid only has order over very short distances, typically a few molecules wide). A mineral is a crystalline substance, a solid in which the atoms have settled into an ordered array that repeats itself off into all directions. Therefore, obsidian is a silicate glass, but not a silicate mineral. It may contain some minerals that were present as suspended particles in the magma before it froze, but the bulk (the matrix or ground mass) of the obsidian is a glass and not a mineral.

Answer 3

Because our creator knew that we would need glass(for cars,boats, tv's, monitors), and since silica is much more readily able to be shaped than rock itself. Just my opinion...

Answer 4

mostly what got stuck with here on earth is sand

just go to beach if you doubt it

sand is mostly silicon, if you ake some boules, then maybe you could even sell it
