What causes a volcano to erupt for kids?
Volcanic eruptions happen when gas bubbles inside magma, or hot liquid rock, expand and cause pressure to build up. This pressure pushes on weak spots in the earth’s surface, or crust, causing magma to exit the volcano.
Can lightning come from a volcano?
For volcanic lightning near the ground, research suggests the cause is the rubbing together of individual ash particles, which builds up enough static electricity to generate a lightning bolt. Scientists think that as the plume of ash and water vapor rises from the volcano, ice begins to form in its highest layers.
