Rock (geology) – Wikipedia
Most rocks contain silicate minerals, compounds that include silica tetrahedra in their crystal lattice, and account for about one-third of all known mineral species and about 95% of the earth’s crust. [6] The proportion of silica in rocks and minerals is a major factor in determining their names and properties. [7]

10(d) Composition of Rocks – Physical Geography
Most rocks are composed of minerals. Minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition. Of course, the minerals found in the Earth’s rocks are produced by a variety of different arrangements of chemical elements.

The Rock Cycle – National Geographic Society
19 oct. 2023There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing or organic material.
