The are forms of silicon dioxide or silicates.
Most of the rocks contain Silicates as the basic material, silicates are anions containing Silicon and oxygen and in combination with metallic cations mostly Calcium and Magnesium.
Igneous rocks are mostly made up of silicate minerals. These silicates are of two types, light and dark silicates. The dark silicates are also called ferromagnesian because of the presence of iron and magnesium in them. They include olivine, pyroxene, amphibole and biotite. The light-colored silicates include quartz, muscovite and feldspar. You can learn more about igneous rocks when you check the link.

Silicate minerals are those composed of silicon and oxygen atoms. Some of these minerals are quartz, feldspar, mica and olivine.
There isn't a specific substance that planets are made of. Most planets are made of solids and/or gases. As far as we know, there may be a planet somewhere out there that's made of liquids.Gases, rocks, and ices
The most common groups of minerals on Earth include silicates, carbonates, oxides, sulfides, and sulfates. Silicates are the most abundant group, making up about 90% of the Earth's crust. Carbonates are commonly found in sedimentary rocks, while oxides, sulfides, and sulfates are often formed through chemical processes involving oxygen and sulfur.
It's safe to say most rocks are chemically silicates, although the commonest rocks contain oxides of calcium, magnesium, and other metals. Recent discoveries indicate the most common rock inside the Earth is a magnesium-iron-silicate, although it is difficult to obtain.
