What triggers volcanoes to erupt?

Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.

What is the chemical reaction of a volcano?

The eruption of the volcano is a chemical reaction because the chemical bonds in the reactants are broken and they change into different substances during the reaction. Baking soda and vinegar are reacting to form sodium acetate, carbon dioxide, and water.

What happens if lightning strikes lava?

The heat and friction create a differential in electric charge that sparks a strike. The lightning zaps in and out of the thick plumes of rising ash, making the ash so hot it sometimes turns into liquid.

Can lightning come from a volcano?

Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice), which generate static electricity within the volcanic plume, leading to the name dirty thunderstorm. Moist convection and ice formation also drive the eruption plume dynamics and can trigger volcanic lightning.
