Since rocks are aggregates of mineral grains or crystals, their properties are determined in large part by the properties of their various constituent minerals.

Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy.

Rocks are made up of different minerals, broken pieces of crystals, or broken pieces of rocks. Some rocks are made of the shells of once-living animals, or of compressed pieces of plants.

Igneous rocks form when melted rock cools and solidifies. Sedimentary rocks form when fragments of other rocks are buried, compressed, and cemented together; or when minerals precipitate from solution, either directly or with the help of an organism.

Rocks are primarily composed of minerals, which are naturally occurring, inorganic solids with a defined chemical composition and a crystalline structure. A mineraloid is a naturally occurring, mineral-like substance that lacks the long-range order characteristic of a true crystal.

Types of Rocks There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth's crust, igneous rocks are volcanic and form from molten material.
