rock classification

Rock classification is the process of grouping rocks based on how they form and their mineral content. There are three main types: igneous (formed from cooled magma or lava), sedimentary (created by layers of material compacted over time), and metamorphic (formed when existing rocks are changed by heat and pressure). These classifications help geologists understand Earth's history and processes. By examining a rock’s texture, mineral composition, and formation method, scientists can accurately categorize it and learn about the environment in which it was created.
