The three-dimensional compositions have more silicon in comparison to those composed of independent tetrahedra.
The silicate minerals refer to the most general of Earth's minerals and involve feldspar, quartz, mica, pyroxene, amphibole, and olivine. On the other hand, the silica tetrahedra composed of oxygen and silicon, produce sheets, chains, and frameworks, and bonds with other cations to produce silicate minerals.
This question refers to a group of minerals known as silicates. Silicates are minerals that contain silicon and oxygen in some proportion. These are the most common minerals in both the Earth's crust and mantle, making up 95% of the crust and 97% of the mantle. Although silicates often have very similar chemical formulas, they polymerize to form a variety of structures. Three-dimensional structures have more silicon than those composed of independent tetrahedra.
