Volcanoes form when molten rock, or magma, from beneath the Earth's crust rises to the surface. This can occur at tectonic plate boundaries, where plates diverge or converge, or over hotspots where magma plumes are present. As the magma erupts, it accumulates and solidifies, building up the volcanic structure over time. The eruptions can vary in intensity and style, leading to different types of volcanoes, such as shield, stratovolcanoes, and cinder cones.
