Rocks are naturally occurring, solid aggregates of one or more minerals or mineraloids.

The study of rocks is called geology. Rocks are important because they provide us with information about the Earth's history, composition, and structure. They are also a valuable source of natural resources, such as building materials, gemstones, and metals.

Rocks can be classified into three main types: igneous, sedimentary, and metamorphic. Igneous rocks are formed when molten rock cools and solidifies. Sedimentary rocks are formed when sediments, such as sand, mud, and gravel, are compacted and cemented together. Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemical reactions.
