Magma from the Earth's core forces its way through cracks in the crust, forming volcanoes at the surface. When a volcano is about to erupt, there are loud noises, shaking ground, and magma building up under the surface. During an eruption, volcanoes expel poisonous gases and destroy everything in their path.
