Types of Rocks - INI
Rocks are broadly classified into three types: igneous rocks formed from cooled magma, sedimentary rocks formed from accumulated soil, sand, and organic remains, and metamorphic rocks formed when existing rocks are altered by heat and pressure. These rocks have a cyclical relationship and can transform into each other through geological processes. Each type has distinct characteristics based on its formation process, structure, and composition, and they are widely used as building materials and resources.
