👉 A volcano is a type of rock formation that consists primarily of lava and magma. The process by which molten rock, including lava and magma, rises to the surface and transforms into ash, dust, and other materials is known as volcanic eruption. This can occur in various locations around the world, from the Earth's mantle to the Earth's surface. Volcanic activity can have both positive and negative impacts on the environment, depending on the type of volcano and the conditions surrounding it.
