Besides lava in the liquid form what else may be emitted by a volcano?

Besides liquid lava, a volcano can emit volcanic gases such as water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. Additionally, it can release ash, which consists of tiny particles of rock and mineral fragments. Volcanic eruptions can also produce pyroclastic flows, which are fast-moving currents of hot gas and volcanic matter. Lastly, large explosive eruptions can launch volcanic bombs and larger rock fragments into the atmosphere.
