Answer: Nearly 90% of the igneous rock-forming minerals are silicates; which means that they make up over 90% of the Earth's crust (oxides are the other dominant mineral group).
Explanation:
Each assemblage of silicate minerals tells us something of the environment in which it was formed. The soil, in which we grow our food, is made up largely of silicates. Bricks, stones, concrete, and glass are either silicates or derived from silicates. The time in our computers and clocks is kept by a silicate mineral.
