- Igneous rocks: Formed from the cooling and solidification of magma or lava. The image shows a volcano (source of lava) and a dark, grainy rock typical of igneous origin.
- Sedimentary rocks: Formed from the accumulation and lithification of sediments. The image depicts layered earth (representing sediment deposition) and a rounded, layered rock sample.
- Metamorphic rocks: Formed when existing rocks are altered by heat, pressure, or chemically active fluids. The image shows a rock with visible foliation or banding, characteristic of metamorphic processes.
