How were earth rocks formed?

Earth rocks were formed through various geological processes over millions of years. Igneous rocks originated from the cooling and solidification of molten magma, while sedimentary rocks were created from the accumulation and compaction of mineral and organic materials. Metamorphic rocks formed when existing rocks underwent transformation due to heat, pressure, or chemically active fluids. These processes are part of the rock cycle, which continually recycles and reshapes Earth's materials.
