Volcanoes are the opening of the Earth’s crust and are usually on high grounds/mountains. They usually form at divergent and convergent boundaries as well as hot spots in the middle of tectonic plates. Tectonic plates are rocks that make up the Earth’s outer shell. Molten rock, gases, and ash can escape from the opening of volcanoes – this mixture is called magma. Volcanoes erupt when magma rises to the surface.

This experiment was inspired by Natural History Museum.
