Igneous rocks form when molten magma cools and solidifies. The process begins with heat melting minerals into magma, which, upon cooling, changes into solid rock. Key properties include a glassy texture, visible air bubbles, and distinct crystals. Additionally, sedimentary rocks are formed through the weathering of existing rocks, where natural forces break apart and transport sediments, leading to their eventual cementation. Understanding these processes enhances our appreciation of geology and Earth's history.
