Volcanic activity plays a significant role in shaping the Earth’s surface, giving rise to various landforms that are broadly categorized as extrusive and intrusive, depending on whether the magma reaches the surface or solidifies beneath it. Extrusive landforms are created when magma emerges as lava, ash, or pyroclastic material, whereas intrusive landforms form when magma cools and solidifies below the Earth's crust. Among extrusive landforms, the most prominent are volcanic cones, including shield volcanoes, composite volcanoes, and cinder cones.
