Volcanoes are geological formations where magma from Earth's mantle reaches the surface, forming lava, ash, and gases. They can be active, dormant, or extinct. Active volcanoes regularly erupt, while dormant ones have paused but may erupt again. Extinct volcanoes haven't erupted in a long time and likely won't. They shape landscapes, create fertile soils, and can pose risks to nearby communities. Volcanoes are studied to understand Earth's interior and predict eruptions.
