Definition of a Rock:
A rock is a naturally occurring solid material found on Earth’s surface composed of minerals or mineral-like substances. It forms through geological processes such as cooling of molten magma, sediment deposition, or metamorphic changes due to heat and pressure. Rocks come in various types, including igneous (formed from cooled magma), sedimentary (formed from compacted sediments), and metamorphic (altered by heat and pressure). They vary in composition, texture, and color, playing a significant role in the Earth’s crust and landscape formation.
